Four-Fermion Interaction Model on ℳ<sup><i>D</i>−1</sup> ⊗ <i>S</i><sup>1</sup>
Four-fermion interaction models are often used as simplified models of interacting fermion fields with the chiral symmetry. The chiral symmetry is dynamically broken for a larger four-fermion coupling. It is expected that the broken symmetry is restored under extreme conditions. In this paper, the f...
