The free energy of dilute Bose gases at low temperatures interacting via strong potentials
S. Fournais, L. Junge, T. Girardot +3
We consider a dilute Bose gas in the thermodynamic limit and prove a lower bound on the free energy for low temperatures which is in agreement with the conjecture of Lee-Huang-Yang…

The Casimir-Polder effect for an approximate Pauli-Fierz model: the atom plus wall case
Marco Olivieri
We study a system composed of a hydrogen atom interacting with an infinite conductor wall. The interaction energy decays like , where is the distance between the atom a…
