Mesoscopic Observables of the Dilute Fermi Gas at Low Energy

Abstract: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--Yang formula, we compute the expectation values of one-body observables on a mesoscopic scale.
