Solution Summary

A detailed solution is given

Solution Preview

At zero temperature the system will be in the ground state. The ground state of a system of N fermions is obtained by letting the fermions occupy the N lowest single particle energy levels (note that fermions must be in different states).

The number of quantum states available for electrons in a volume V and volume V_p in momentum space is:

2 V/h^3 Vp

The factor 2 arises from the fact that the electron has ...
