Pressure of Coulomb systems with volume-dependent long-range potentials
A. S. Onegin, G. S. Demyanov, P. R. Levashov
In this work, we consider the pressure of Coulomb systems, in which particles interact via a volume-dependent potential (in particular, the Ewald potential). We confirm that the ex…

Density of states of a 2D system of soft--sphere fermions by path integral Monte Carlo simulations
V. Filinov, P. Levashov, A. Larkin
The Wigner formulation of quantum mechanics is used to derive a new path integral representation of quantum density of states. A path integral Monte Carlo approach is developed for…
