Finite-size, chemical-potential and magnetic effects on the phase transition in a four-fermion interacting model

Abstract We study effects coming from finite size, chemical potential and from a magnetic background on a massive version of a four-fermion interacting model. This is performed in four dimensions as an application of recent developments for dealing with field theories defined on toroidal spaces. We...
