Abstract

A mechanism generating a λ-type behavior in the specific heat of a Bose gas near the critical temperature T_c is discussed. It is shown to work for a general class of quasiparticle spectra, and especially, for the Bogoliubov's model of a weakly interacting Bose gas, where a temperature-dependent quasi-particle spectrum is obtained.
