Spectral Function and Kinetic Equation for Normal Fermi Liquid
On the basis of the Kadanoff-Baym (KB) version of the time-dependent Green’s function method a new ansatz for the approximation of a spectral function is offered. The ansatz possesses all the advantages of quasiparticle (QP) and extended quasiparticle (EQP) approximations and satisfies the KB-equation for a spectral function in the case of slightly non-equilibrium system when disturbances in sp...
متن کاملKinetic Equations in the Theory of Normal Fermi Liquid
On the bases of the improved approximation for the spectral function of oneparticle states the Landau-Silin kinetic equations for the normal Fermi liquids of neutral and electrically charged particles are shown to be valid at finite temperature above the temperature of superfluid transition.
متن کاملBifurcation in kinetic equation for interacting Fermi systems.
The recently derived nonlocal quantum kinetic equation for dense interacting Fermi systems combines time derivatives with finite time stepping known from the logistic mapping. This continuous delay differential equation is a consequence of the microscopic delay time representing the dynamics of the deterministic chaotic system. The responsible delay time is explicitly calculated and discussed f...
متن کاملUsing Hermite Function for Solving Thomas-Fermi Equation
In this paper, we propose Hermite collocation method for solving Thomas-Fermi equation that is nonlinear ordinary differential equation on semi-infinite interval. This method reduces the solution of this problem to the solution of a system of algebraic equations. We also present the comparison of this work with solution of other methods that shows the present solution is more accurate and faste...
متن کاملA quantum kinetic equation for Fermi-systems including three-body correlations
A single-time quantum transport equation, which includes effects beyond the quasiparticle approximation, is derived for Fermi-systems in the framework of non-equilibrium real-time Green’s functions theory. Ternary correlations are incorporated in the kinetic description via a cluster expansion for the self-energies (e.g., the transport vertex and the width) truncated at the level of three-body ...
