The Chiral Gross-Neveu model on the lattice via a Landau-forbidden phase transition

Gertian Roose, Jutho Haegeman, Karel Van Acoleyen +2

We study the phase diagram of the $(1+1)$-dimensional Gross-Neveu model with both $g_x^2(\bar{\psi }\psi {)}^2$ and $g_y^2(\bar{\psi }i{\gamma }_5\psi {)}^2$ interaction terms on a spatial lattice. The continuous…
