Fermions in a two-level or three-level system with degeneracy consider a have only two energy levels, with energy eo = degeneracies no and n1, which are integers. hint: note that system of n independent fermions. assume that single-particle hamiltonian 0 and e1 = €. however, the two levels have 1 1 (4) e 1 e- 1 a) for the case of n = 1 = no = n1. find the chemical potential, u, as a function of temperature. find the fermi energy, ef t0) (b) for the case of n no, while no and ni are arbitrary integers. find the chemical potential, , as a function of temperature in the low temperature limit.
