Sensitivity of solid phase stability to the interparticle potential range: studies of a new Lennard-Jones like model
Olivia S. Moro, Vincent Ballenegger, Tom L. Underwood +1
In a recent article, Wang et al (Phys. Chem. Chem. Phys., 22, 10624 (2020)) introduced a new class of interparticle potential for molecular simulations. The potential is defined by…
The dilute interacting Bose gas : comparisons between Feynman diagrammatic expansion and the hierarchy equations for the imaginary time Green functions
Victor Dansage, Vincent Ballenegger, Angel Alastuey
We analyze the correspondence between two formalisms describing an interacting Bose gas, namely the standard Feynman diagrammatic expansion on the one hand, and the hierarchy equat…
Screened activity expansion for the grand-potential of a quantum plasma and how to derive approximate equations of state compatible with electroneutrality
A. Alastuey, V. Ballenegger, D. Wendland
We consider a quantum multi-component plasma made with S species of point charged particles interacting via the Coulomb potential. We derive the screened activity series for the pr…
Screened activity expansion for the pressure of a quantum multi-component plasma and consistency with the local charge neutrality
A. Alastuey, V. Ballenegger, D. Wendland
We consider a quantum multi-component plasma made of point charged particles interacting via the two-body Coulomb potential. Within the Feynman-Kac path integral representation of…
Structure and dielectric properties of polar fluids with extended dipoles: results from numerical simulations
V. Ballenegger, J. P. Hansen
The strengths and short-comings of the point-dipole model for polar fluids of spherical molecules are illustrated by considering the physically more relevant case of extended dipol…
Local dielectric permittivity near an interface
V. Ballenegger, J. -P. Hansen
A statistical mechanics expression is derived for the space-dependent dielectric permittivity of a polar solvent near an interface. The asymptotic behaviour of this local permittiv…
