Mott transition and integrable lattice models in two dimensions
Federico L. Bottesi, Guillermo R. Zemba
We describe the two-dimensional Mott transition in a Hubbard-like model with nearest neighbors interactions based on a recent solution to the Zamolodchikov tetrahedron equation, wh…

Effective Field Theories for Electrons in Crystalline Structures
Federico L. Bottesi, Guillermo R. Zemba
We present an effective field theory formulation for a class of condensed matter systems with crystalline structures for which some of the discrete symmetries of the underlying cry…
