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…
Algebraic infection of charge correlations of a classical electrolyte at the critical point of the liquid-gas transition
Angel Alastuey, Subir Das
We consider a classical Two-Component Plasma analog of the Restricted Primitive Model of electrolyte, where the hard-core interaction is replaced by a soft differentiable potential…
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…
Hartree-Fock analysis of the effects of long-range interactions on the Bose-Einstein condensation
A. Alastuey, J Piasecki, P. Szymczak
We consider a Bose gas with two-body Kac-like scaled interactions V (r) = 3 v(r) where v(x) is a given repulsive and integrable potential, while is a positive parame…
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…
Fourth moment sum rule for the charge correlations of a two-component classical plasma
Angel Alastuey, Riccardo Fantoni
We consider an ionic fluid made with two species of mobile particles carrying either a positive or a negative charge. We derive a sum rule for the fourth moment of equilibrium char…
