Magnetic Catalysis of Parity Breaking in a Massive Gross-Neveu Model and High-Temperature Superconductivity
Protvino, 2000.-p.8, figs.2, tables 1, refs.:21.


In the framework of a (2+1)-dimensional P-even massive Gross-Neveu model, an external magnetic field is shown to induce a parity breaking first order phase transition. Possibility of applying the results obtained to description of magnetic phase transitions in high-temperature superconductors is discussed.
