A wide-range temperature-dependent deep potential for sodium with near-experimental accuracy from melting to the critical point
G. S. Demyanov, D. V. Minakov, V. B. Fokin +1
We construct temperature-dependent deep potentials for sodium using finite-temperature DFT data obtained with the PBE, AM05, and SCAN exchange-correlation functionals and inve…

One--Component Plasma Equation of State Revisited via Angular--Averaged Ewald Potential
G. S. Demyanov, P. R. Levashov
We present analytic fits of classical one--component plasma (OCP) internal energy over a wide range of coupling parameter using Monte--Carlo data in the thermodyn…

Molecular dynamics of nondegenerate hydrogen plasma using improved Kelbg pseudopotential with electron finite-size correction
G. S. Demyanov, P. R. Levashov
This paper is devoted to semiclassical molecular dynamics simulation of nondegenerate hydrogen plasma using an improved Kelbg pseudopotential. The main novelty of our method is acc…
