    Finite density and temperature in hybrid bag models
    (1999) De Francia, M; Falomir, H; Loewe, M
    We introduce the chemical potential in a system of two-flavored massless fermions in a chiral bag, with an external Skyrmion, by imposing boundary conditions in the Euclidean time direction. We express the fermionic mean number in terms of a functional trace involving the Green function of the boundary value problem, which is studied analytically. Numerical evaluations for the fermionic number are presented. [S0556-2813(99)04310-1].
