Title THE EFFECTIVE INTERPARTICLE SCREENING AND THE LOCAL-FIELD CORRECTION IN THE SPIN-POLARIZED ELECTRON-SYSTEM
Author(s) IVLIEV, SV; SOBAKIN, VN
Source PHYSICA STATUS SOLIDI B-BASIC RESEARCH 164 (2):453-462 1991
Times Cited 0
Abstract The screening properties of a system of interacting spin-polarized electrons are investigated. The exact closed equation for the vertex function is received by a many-particle approach and the main contribution to that function is founded on the linear approximation of the generalized screened potential. The local field factor is calculated and its strong electron density dependence is demonstrated. The compressibility is positive in a wide interval of electron densities.

AbstractThe screening properties of a system of interacting spin-polarized electrons are investigated. An exact closed equation for the vertex function is obtained in the many-particle approach, and the decisive contribution arising in the ladder approximation with respect to the generalized screening potential is found. The local field correction, which depends strongly on the electron density and ensures positive compressibility in a broad range of electron densities, is calculated.

Abstract We use the saddle-point method to derive analytical expressions for the spectral-angular probability distributions of the ionization by a strong linearly polarized laser field in Keldysh's model that are valid for an arbitrary electron energy and adiabaticity parameter. We obtain asymptotic expansions of the general formulas in the multiphoton and tunneling regimes, analyze their accuracy, and formulate the validity conditions. We provide literal estimates of the parameters that characterize the properties and evolution of the distributions. (C) 2005 Pleiades Publishing, Inc.

AbstractThe S-matrix formalism for non-sequential double ionization (NSDI) in a rescattering scenario is further explored with two objectives in mind. First, two different forms of the electron-electron correlation are compared: the Coulomb repulsion and a three-body contact interaction including the ion, both in the Born approximation. The former favours disparate momenta of the two electrons, the latter equal momenta. Second, the analogue of the intensity-dependent resonances in above-threshold ionization spectra is investigated in the case of NSDI. For the Coulomb electron-electron interaction, a distinct signature is observed in the momentum distributions of the final two electrons.

AbstractA study is made of the nonadiabatic dynamics of photoelectrons produced during interaction of an elliptically polarized, high-power laser pulse with a gas. Expressions for the so-called residual momentum and energy of the electrons (i.e., the mean electron momentum and energy after the passage of the pulse through the gas) are derived. The residual electron momentum and energy are investigated analytically as functions of the gas and laser parameters. A relationship is established between the residual energy and the electron temperature tenser. (C) 2001 MAIK "Nauka/Interperiodica".

AbstractNon-sequential double ionization of atoms in a strong Linearly polarized laser field is studied on the basis of the generalized Keldysh model. The transition amplitude is calculated using a saddle-point method and the distribution in the total and relative momenta of two emitted electrons is found in an analytical form. The obtained result is compared with that from the simple-man approach. By integrating over the relative momentum we calculate the distribution in the total momentum. Its shape with two maxima and their positions are in good agreement with recent experimental measurements and elaborate numerical calculations of the recoil momentum distribution for doubly charged ions. We show that positions of the maxima depend strongly on the differential cross section of (e --> 2e) inelastic collisions.

AbstractWe compare the spectral-angular distributions of photoelectrons in a high-energy plateau of above-threshold ionization calculated in the tunneling limit within the framework of a semiclassical three-step model and obtained by the saddle-point method. It is demonstrated that both procedures of calculations give mathematically equivalent results, adequately describing the distribution of photoelectrons within the range predicted by the three-step model, but become inapplicable near the boundaries of this range.

AbstractA generalized Keldysh model is used to obtain simple analytical expressions for the energy and angular distributions of photoelectrons rescattered by the parent ion. The dependence of the form, absolute magnitude, and interference structure of the distributions on the parameters of the field and atom is investigated. It is shown that even though the semiclassical three-step rescattering model determines correctly the position of the boundaries beyond which the distributions decay rapidly, the model itself is inapplicable near them.

AbstractWe consider classical emission of a relativistic electron moving in an arbitrary direction with respect to the direction of propagation of a strong circularly polarized electromagnetic wave. The exact expression for the angular distribution is derived by the summation of harmonics in the spectral-angular distribution.

AbstractAsymptotic expansions of the Jacobi polynomials P-n((alpha,beta))(cos theta) have been derived for the case when the parameters n, alpha, beta are large and comparable in magnitude. The expansions have different forms in the middle of the interval 0 < theta < pi and near the limiting points theta = 0 and theta = pi. They turn into the previously known results if n much greater than alpha, beta, The obtained expressions could be used for analytic calculation and numerical computation of the atomic dipole matrix elements between Rydberg states in an extended range of quantum numbers.

AbstractThe distribution of photoelectrons over momenta is derived in a closed form for the tunneling regime of ionization by an elliptically polarized laser field. It is demonstrated that, as the polarization changes from circular to linear, within a broad range of ellipticity, the angular distribution is stretched along the small axis of the polarization ellipse, in the direction transverse to the maximum electric field. Only when the ellipticity is rather small, the distribution is modified and becomes stretched along the electric field, as it should be in a linearly polarized field.

Abstract The effect of the field-induced broadening of harmonics radiated by an electron in the field of a high-intensity focused laser pulse was investigated. Broadening is caused by ponderomotive scattering, which continuously changes the average velocity of the electron and thus modulates the Doppler frequency shift of harmonics in the laboratory frame of reference. At relativistic intensities, broadened harmonics overlap, yielding a continuous radiation spectrum. This paper proposes a modification of the averaging procedure, which yields equations governing the averaged motion of an electron in the strong field of a focused pulse, with the dimensionless intensity parameter higher than, or of the order of, unity.

Abstract The electric-field distribution in QED and the gluoelectric-field distribution in QCD are determined near the corresponding static external sources. These field distributions are determined by the free and bound charges present in the vacuum as a result of the presence of the sources. The distributions of the electric and gluoelectric fields near two static sources of equal and opposite electric and color charge are also determined with allowance for the dielectric properties of the vacuum, as well as the electron and quark condensate.

AbstractVarious processes of pion production in nuclear matter at characteristic temperatures T much less than m(pi) are analyzed. It is shown that the pions are produced mainly in NN --> NN(pi) reactions. Taking into account the modification of the NN interaction in nucelar matter, probabilities and differential cross sections of production of pi- mesons in direct NN --> NNpi- reactions are calculated. It is shown that at incident-pion momenta q approximately 2m(pi) processes with pion production via DELTA-resonance intermediate states dominate. From a comparison of the results of the calculation with experimental data on pion production in nucleus-nucleus collisions it is concluded that piN absorption is strong and increases with increasing temperature and density of the nuclear matter. At the initial stage of development of the nuclear fireball the pions are confined inside the system at practically all momenta. Soft (q less-than-or-similar-to m(pi)) pions are emitted at the intermediate stage of expansion of the nuclear fireball, and harder pions are released together with nucleons at the final stage of breakup of the fireball.

AbstractThe results of the thermodynamical approach to the description of nuclear collisions at energies below a few GeV/nucleon with inclusion of polarization effects of the heated nuclear medium are presented. Arguments are given for the need to include collective effects. The initial scenario of the nucleus-nucleus collision based on the model of an expanding nuclear fireball is formulated. Mean free paths of the nucleon and pion quasiparticles are calculated with allowance for collective effects in the heated nuclear medium. It is found that they are considerably shorter than those predicted by the gas model. The effects of softening of the pion degree of freedom in the nuclear medium in the dynamics of expansion of the nuclear fireball are taken into account. Compact expressions are derived for the differential cross sections for pion production with inclusion of the effects of the medium in its fast breakup. The effects of softening of the pion degree of freedom are taken into account in calculations of the thermodynamical characteristics of the system. By comparing the theoretical and experimental data, the phenomenological equation of state of the heated dense nuclear matter is reproduced. Occupation of the pion and DELTA-isobar branches of the spectrum of pion excitations at T not-equal 0, as well as the existence of the liquid phase of the pion condensate at rho > rho(c1) approximately 0.5-0.7-rho-0(rho-0 congruent-to 0.17 fm-3 is the nuclear density), which corresponds to the appearance of a large number of virtual pion quasiparticles with nonzero momentum (k not-equal 0) corresponding to the low-lying spin-isospin branch of excitations, are taken into account. In accordance with experiment, the compressibility of cold nuclear matter is taken to be equal to 210 MeV. The role of the polarization effects of the nuclear medium in calculating the yields of nucleons is examined. The puzzle of the large entropy is solved in principle. The role of the medium effects in production of photons, whose mean free path is longer than that of the pions and nucleons, is studied. The mean free path of the photons is determined. It is found that high-frequency photons (omega > T) are emitted during the hot initial stage of a nuclear collision. Their differential cross sections are determined by the total NN interaction amplitude in the nuclear medium. In a certain frequency interval (omega < T) the photons are confined inside the nuclear fireball before its breakup. The principal expressions determining the NN interaction amplitude and the pion polarization operator in a heated dense nuclear medium with equal isotopic contents (N = Z) are given in appendices.

AbstractArguments are given for the condensation of electrons from the lower continuum in the field that arises at ultrashort distances from a positively charged center. In the quasiclassical approximation an equation is derived for the vacuum-charge distribution near a bare charge source of arbitrary radius with allowance for the dielectric properties of the vacuum (epsilon(ren) not-equal 1) and electron condensation. Near a source with radius r0 r(m) greater than or similar to r(epsilon)(r(m) approximately r(epsilon)exp[3piZ(obs)/square-root 2(1+2(Z(obs)e2)2)1/2], where Z(obs) > 0 is the nuclear charge observed at r --> infinity) condensation of electrons occurs on levels that have dropped from the upper continuum below the boundary omega 0. With increase of the distance from the center, Q 2(r) increases and reaches its maximum value 1/2 at r approximately r(epsilon), and then falls to the value Z0 2e4/[1 + 2(Z0e2)2] at r approximately 1/m. Arguments are given that QED is logically closed as a theory with a point interaction with a consistent renormalization of the electron charge and with an electron mass of electromagnetic origin.

AbstractWe study photon production in nucleus-nucleus collisions at energies E(lab) approximately-greater-than 1 GeV/nucleon. We estimate the mean free path of the photons. It is found that photons with frequency omega(gamma) > T(m), where T(m) is the temperature of the nuclear fireball at the instant of maximum compression, are produced mainly in direct reactions np --> np-gamma, after which they leave the system freely. In the thermodynamical approach we include multiple np collisions. We analyze the differential cross sections for the photons. They are estimated quantitatively with allowance for the total NN interaction amplitude in nuclear matter, parametrized in the theory of finite Fermi systems. The estimated dependence of the cross section on the energy of the emitted photons omega(gamma) is in agreement with experiment. From a comparison with experiment it is also possible to estimate the total time of expansion of the nuclear fireball t(o) until its breakup. It is found that photons with frequency omega(gamma) < T(b), where T(b) is the temperature at the instant of breakup of the nuclear fireball, are confined inside the nuclear system for t < t(o). They become free at t congruent-to t(o) and T(t(o)) congruent-to T(b). We determine the differential cross section for the production of these photons with allowance for their polarization in nuclear matter.

Abstract The distribution function of the scattered radiation intensity is calculated in the approximation of the basic polarization modes. In such an approximation, the distribution function is represented in terms of the degree of polarization of the initially circularly and linearly polarized waves transmitted by the sample. The effect of the difference of the decay rates for the circular and linear polarization modes on the statistics of the light waves that are multiply scattered in the medium with large inhomogeneities is analyzed.

AbstractApproximate analytical expressions for the intensities of the polarized components of light reflected from a disordered medium with larcye discrete particles (larger than the wavelength) have been derived with the use of the method of decoupling of the vector transfer equation that is based on separate treatment of basic and additional polarization modes. The results obtained provide the relation between the peak shape in the angular distribution of the backscattered radiation with a given polarization and the optical characteristics of the medium and are in good agreement with experimental data and numerical calculations.

AbstractIt is shown that multiple scattering of polarized light in a turbid medium can be represented as independent propagation of three basic modes: intensity and linearly and circularly polarized modes. Weak interaction between the basic modes can be described by perturbation theory and gives rise to "overtones" (additional polarization modes). Transport equations for the basic and additional modes are derived from a vector radiative transfer equation. Analytical solutions to these equations are found in the practically important cases of diffusive light propagation and small-angle multiple scattering. The results obtained are in good agreement with experimental and numerical results and provide an explanation for the experimentally observed difference in depolarization between linearly and circularly polarized waves.

AbstractAn approximate analytical method was developed for solving the vector equation describing radiative transfer in an optically isotropic medium with large-scale inhomogeneities. The method is based on the assumption that the phase function of single scattering is strongly elongated in the forward direction. The method is illustrated by an analysis of propagation of a broad linearly polarized beam within the small-angle diffusion approximation with allowance for two basic depolarization mechanisms (geometrical and dynamic mechanisms).

AbstractIn a medium with large (larger than a wavelength) spherical inhomogeneities, two reasons for depolarization of light can be distinguished. The "geometrical" mechanism of depolarization is shown to dominate in multiple scattering of linearly polarized light. Depolarization processes of "dynamical" origin are less pronounced, resulting in the effect of slow decay of circular polarization (polarization can persist even after the radiation flux is isotropized). The difference in the rates between the "geometrical" depolarization and the "dynamical" one allows us to develope an iterative procedure for solving the vector radiative transfer equation and to calculate the Stokes parameters of polarized light.

AbstractSmall-angle multiple scattering of circularly polarized waves in disordered systems composed of large (larger than the light wavelength) spherical particles is discussed. The equation for Stokes's fourth parameter V - the difference between the intensities of the left- and right-hand polarized light - is shown to have the form similar to that of the scalar transport equation for intensity I, the only difference being the presence of an additional "non-small-angle'' term responsible for depolarization. In the case of small-angle scattering, depolarizing collisions are relatively rare and, in contrast to the scalar case, the problem contains an additional spatial scale, namely the depolarization depth. The polarization degree and helicity of the scattered light are calculated for the case of purely elastic scattering and in the presence of absorption in the medium. For strong absorption, depolarization is shown to follow the transition to the asymptotic regime of wave propagation. The features appearing in strong (non-Born) single scattering are also discussed.

AbstractThe decay of light linear polarization by multiple scattering in a random medium with large-scale inhomogeneities is considered. The small-angle vector transport equation is derived. The Stokes parameters in the small-angle diffusion approximation are calculated. It is shown that there is a qualitative difference in decay mechanisms for circular and linear polarization: the circular polarization decays much slower than the linear polarization.

AbstractIt is shown that in the presence of diffusion of electromagnetic waves in random media containing large discrete scatterers, circular polarization can persist even after the radiation flux is isotropized. For scattering exactly in the backward direction, this effect is manifested as an increase in the interference contribution to the cross-polarized component of the intensity as the size of the scatterers increases.

AbstractThe Stokes parameters are calculated for a multiply scattered optical pulse propagating through a medium with large-scale inhomogeneities. The temporal behavior of the intensity and the degree of polarization is studied for phase functions decreasing with scattering angle by a power law. It is shown that the exponent of the power law can have a determining effect on the time dependence of the degree of polarization. This dependence can turn nonmonotone with an increase in the scale of inhomogeneitie.

Abstract The solution of vector radiative transfer equation is found for the case of normal incidence of a wide non-polatized light beam at a medium with large-scale inhomogeneities. The generalization of the well-known Small angle solution for the Stocks parameters of light transmitted through relatively thin layers, where photon trajectories curvature is negligible, is obtained; A qualitative description of the formation of light polarization in absorbing media is presented. The dependence of light polarization on the form of the scattering indicatrix is analyzed in details.

AbstractWe obtain an exact analytical solution to the problem of the enhanced backscattering of a short pulsed signal from a two- and three-dimensional medium with isotropically scattering centres. The angular spectrum is expressed in terms of the solution to the corresponding stationary problem. The intensity oscillations are shown to appear on the tails of the angular spectrum. The origin of these oscillations is associated with the ballistic phase shift between the interfering waves arriving at the detector. It is shown that the finiteness of the slab thickness influences the magnitude of the backscattering intensity and does not change the shape of the angular spectrum. The range of validity for the diffusion approximation is pointed out. The results obtained in the paper also contain a generalization of the well known solution to the problem of incoherent transfer of a pulsed signal to the case of two-dimensional disordered media.

AbstractA consistent theory of spatial fluctuations of irradiance under a wavy sea surface is developed. Principal physical factors that govern the value of irradiance are taken into account. For various models of surface waves, irradiance fluctuations are studied in detail. The effects of underwater scattering and absorption of light, and of the spatial coherence of incident light beam, on the irradiance spectrum are studied. It is shown that various regions of the Pirson-Moskovitz wave spectrum play essentially different roles in forming the spatial fluctuations and depth behavior of scintillation index. Validity limits of geometrical optics are determined. The dependence of the spatial spectrum of underwater irradiance on surface wave parameters (wind velocity etc.) and on optical characteristics of water (scattering and absorption coefficients etc.) is found. A number of new effects concerning the depth behavior of scintillation index and fluctuation spectrum is predicted. Obtained theoretical results agree with the experimental data.

AbstractElectron enhanced backscattering in a uniform magnetic field H is studied. Under weak localization conditions (p0l much greater than 1, p is the electron moment, l is the mean free path), an analytical expression for the angular spectrum of backscattered electrons is found. The various H orientations (Hn = 0, [Hn] = 0, n is the normal to a surface) in the cases of 2D- and 3D-disordered semi-infinite systems are considered. It is shown that the quantum interference destruction in a magnetic field gives rise to blunting of the backscattering peak. We have found asymmetry of the angular spectrum and unexpected peak deviation from the exact backward direction. The angular deviation is determined by the average magnetic flux through the contour formed by electron time-reversed trajectories. Generalization of the results, taking into account inelastic electron collisions, is also discussed.

AbstractThe interference contribution to the angular spectrum of the charged particle backscattering by a 3D and 2D disordered systems in uniform magnetic field is calculated under a weak localization condition. Besides blunting of the spectrum peak due to breaking the coherence of the time-reversed waves it is shown that the spectrum asymmetry may be observed as well. In the case of magnetic field parallel to the medium surface the peak of the angular spectrum of the backscattered particles shifts with respect to the exact backward direction. The shift magnitude is governed by the average magnetic flux through the contour formed by the time-reversed trajectories of backscattered particles.
