Justification of c-number substitutions in bosonic Hamiltonians.

Abstract

The validity of substituting a c-number z for the k=0 mode operator a(0) is established rigorously in full generality, thereby verifying one aspect of Bogoliubov's 1947 theory. This substitution not only yields the correct value of thermodynamic quantities such as the pressure or ground state energy, but also the value of |z|(2) that maximizes the partition… (More)
