Stability of a Nondegenerate Two--Component Weakly Coupled Plasma
G. S. Demyanov, P. R. Levashov
The paper discusses the problem of stability of a two-component plasma and proposes a consistent consideration of quantum and long-range effects to calculate the thermodynamic prop…
A wide-range semiclassical self-consistent average atom model
A. S. Polyukhin, S. A. Dyachkov, P. R. Levashov
Discovery of material properties at extremes, which are essential for high energy density physics development, requires the most advanced experimental facilities, theories, and com…
One--Component Plasma of a Million Particles via angular--averaged Ewald potential: A Monte Carlo study
G. S. Demyanov, P. R. Levashov
In this work, we derive a correct expression for the one--component plasma (OCP) energy via the angular--averaged Ewald potential (AAEP). Unlike E.~Yakub and C.~Ronchi (J. Low Temp…
Derivation of the Kelbg potential/functional
G. S. Demyanov, P. R. Levashov
The density matrix for a system of particles interacting via the Coulomb potential is obtained in the high--temperature limit following almost entirely the original work by Kelbg.…
Systematic derivation of angular--averaged Ewald potential
G. S. Demyanov, P. R. Levashov
In this work we provide a step by step derivation of an angular--averaged Ewald potential suitable for numerical simulations of disordered Coulomb systems. The potential was first…
Monte Carlo simulations of the electron short-range quantum ordering in Coulomb systems: Reducing the "fermionic sign problem"
Vladimir Filinov, Pavel Levashov, Alexander Larkin
To account for the interference effects of the Coulomb and exchange interactions of electrons a new path integral representation of the density matrix has been developed in the can…
