Two-level bosonic model that simulates the transition from a superconductive condensate to an alpha cluster condensate

A simple bosonic model that has two different phases, one corresponding to a condensate of bosons, a situation that resembles spherical nuclei, and a second one of a condensate of pairs of bosons that corresponds to nuclei where the ground state is a condensate of alphalike clusters, is solved in se...

Sumario:A simple bosonic model that has two different phases, one corresponding to a condensate of bosons, a situation that resembles spherical nuclei, and a second one of a condensate of pairs of bosons that corresponds to nuclei where the ground state is a condensate of alphalike clusters, is solved in several different approximate treatments and exactly. Some differences due to the finite number of bosons from the known results for large boson systems are obtained. © 1989 The American Physical Society.
