Abstract:
It is proved on the basis of Galilean invariance that a degenerate liquid of identical interacting Fermions possesses excited states corresponding to arbitrarily small energies of excitation. Thus there is no energy gap in the spectrum of infinite nuclear matter and there is an essential difference between nuclear matter and the electron gas in a superconductor. In the latter the lattice provides a preferred frame of reference so a gap in the energy spectrum is not ruled out by considerations based on Galilean invariance. Author
