Do correctly. Will rate. Due by Saturday evening

a = 12.1. We consider a free gas of spin 1/2 fermions in a finite volume V = L with periodic boundary conditions. This implies the constraints ki = 2 -Ni, N; EZ L on the components of the wave vector. = Our fermion gas contains N 1 particles, and we assume it to be in the state of minimal energy. How large is the maximal momentum pe kf (the Fermi momentum) in the fermi gas? You have to take into account that only two fermions can have the same momentum
