The magnetized Gross-Neveu model at finite chemical potential
Michael Mandl, Julian J. Lenz
We study the (2+1)-dimensional Gross-Neveu model at non-zero chemical potential and subjected to a homogeneous background magnetic field. We do so both analytically, in the limit o…

The magnetized (2+1)-dimensional Gross-Neveu model at finite density
Julian J. Lenz, Michael Mandl, Andreas Wipf
We perform a lattice study of the ()-dimensional Gross-Neveu model in a background magnetic field and at non-zero chemical potential . The complex-action problem arisin…

Magnetic catalysis in the (2+1)-dimensional Gross-Neveu model
Julian J. Lenz, Michael Mandl, Andreas Wipf
We study the Gross-Neveu model in dimensions in an external magnetic field . We first summarize known mean-field results, obtained in the limit of large flavor number $N_\…
