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…
