Bosonized Momentum Distribution of a Fermi Gas via Friedrichs Diagrams

Sascha Lill

Recently, Benedikter and the author proved an approximate formula for the momentum distribution of a 3d fermionic gas interacting by a short-range pair potential in the mean-field…

Momentum Distribution of a Fermi Gas in the Random Phase Approximation

Niels Benedikter, Sascha Lill

We consider a system of interacting fermions on the three-dimensional torus in a mean-field scaling limit. Our objective is computing the occupation number of the Fourier modes in…
