Abstract

We propose an exact solution of a model describing a low energy behavior of cold isospin S=3/2 fermionic atoms on a one-dimensional optical lattice. Depending on the band filling the effective field theory has a form of a deformed Gross-Neveu model with either O(7)×Z2O(7)\times \mathbb{Z}_2 (half filling) or U(1)×O(5)×Z2U(1)\times O(5)\times \mathbb{Z}_2 symmetry.
