- lambda - type phase transition for a weakly interacting bose gas I. Cabrera D. Oliva H. Pérez Rojas Física, Astronomía y Matemáticas It is suggested a general mechanism through which a lambda-type behavior is produced in the specific heat of a Bose gas near the critical temperature Tc . It is essential that the quasiparticle spectra have a gap proportional to the condensate. It works for a general class of quasiparticle spectra, and in particular, for the weakly interacting Bose gas. The introduction of a chemical potential in the theory is briefly discussed. 2001 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46413504001 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.4 Vol.31
