Abstract:
The thermal mean-field (Hartree-Bose-Bogoliubov) approximation is applied to a simple bosonic model that is related to the phase transition from spherical to deformed nuclei. Similarities and differences with the time-dependent approach are discussed, in particular, the sensitivity of each method for the detection of the phase transition.
