Self-consistent Ornstein-Zernike approximation for three-dimensional spins
An Ornstein-Zernike approximation for the two-body correlation function embodying thermodynamic consistency is applied to a system of classical Heisenberg spins on a three-dimensional lattice. The consistency condition determined in a previous work is supplemented by introducing a simplified expression for the meansquare fluctuations of the spin on each lattice site. The thermodynamics and the ...
متن کاملA Self-Consistent Technique for the Construction and Evaluation of the Three-Parameter Corresponding States Principles
A self-consistent approach for the evaluation of the existing three-parameter corresponding states principles of non-polar fluids and the calculation of the corresponding states parameters is presented. This self consistent approach is based upon the assumption that the contribution of the third parameter to the thermophysical properties is much smaller than the contributions of the first two p...
متن کاملsiparticle Self . Consistent GW Approximation
We present a new ab initio method for electronic structure calculations of materials at finite temperature (FT) based on the all-electron quasiparticle self-consistent GW (QPscGW) approximation and Keldysh time-loop Green's function approach. We apply the method to Si, Ge, GaAs, InSb, and diamond and show that the band gaps of these materials universally decrease with temperature in contrast wi...
متن کاملSelf-consistent random-phase approximation for a two-dimensional electron gas: Kadanoff-Baym-Keldysh approach
We have developed a method of finding equilibrium Green’s functions for an electron gas with Coulomb interaction within the Kadanoff-Baym-Keldysh approach. This method is based on iterative numerical computation of the retarded self-energy in the self-consistent random-phase approximation. For a two-dimensional electron gas, we have calculated numerically various one-electron properties and the...
متن کاملSelf-consistent random-phase approximation for a two-dimensional electron gas at finite temperatures
For a two-dimensional electron gas with Coulomb interaction, we have applied the Kadanoff-Baym-Keldysh approach to calculate numerically equilibrium Green’s functions at finite temperatures. The method used is based on iterative numerical computation of the retarded self-energy in the self-consistent random-phase approximation approximation. We have computed electron distribution, quasiparticle...
