Mesoscopic Observables of the Dilute Fermi Gas at Low Energy
Niels Benedikter, Emanuela L. Giacomelli, Asbjørn Bækgaard Lauritsen +1
We consider a dilute quantum gas of interacting spin-1/2 fermions in the thermodynamic limit. For a trial state that resolves the ground state energy to the precision of the Huang-…
Momentum Distribution of a Fermi Gas with Coulomb Interaction in the Random Phase Approximation
Niels Benedikter, Sascha Lill, Diwakar Naidu
We analyse the momentum distribution of a three-dimensional Fermi gas in the mean-field scaling regime in a trial state that was recently proven to reproduce the Gell-Mann-Brueckne…
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…
