Random phase approximation (RPA) was proposed by Bohm and Pines in four seminal papers during 1951-1953 to describe the correlation of fermions, namely the correction to the Hartree-Fock theory. While...

We present a technique which allows us to solve the Random Phase Approximation equations
with finite-range interactions and treats the continuum part of the excitation spectrum without
approximation...

Evaluation of ground state entanglement in spin systems with the random phase approximation
Evaluation ground state entanglement spin systems random phase approximation
2010/10/19
We discuss a general treatment based on the mean field plus random phase approximation (RPA)
for the evaluation of subsystem entropies and negativities in ground states of spin systems. The approach ...
Random Phase Approximation in Relativistic Approach
fully consistent RRPA coupling to the continuum pairing correlation
2009/10/28
Some special issues of the random phase approximation(RPA) in the relativistic approach are reviewed. A full consistency and proper treatment of coupling to the continuum are responsible for the succe...

Electron Liquid Beyond the Random Phase Approximation
three-dimensional two-dimensional Electron Liquid
2010/4/16
A deeper understanding of low-dimensional and small-scale electronic systems requires an accurate characterization of the many-electron effects. Based on the electron liquid (EL) model, these many-bod...
