Converging finite-temperature many-body perturbation theory that conserves the average number of electrons
So Hirata, Punit K. Jha
A finite-temperature perturbation theory for the grand canonical ensemble is introduced that expands chemical potential in a perturbation series and conserves the average number of…

Numerical Evidence Invalidating Finite-Temperature Many-Body Perturbation Theory
Punit K. Jha, So Hirata
Low-order perturbation corrections to the electronic grand potential, internal energy, chemical potential, and entropy of a gas of noninteracting, identical molecules at a nonzero…
