Abstract

Mott transitions are studied in the two-dimensional Hubbard model by a non-perturbative theory of correlator projection that systematically includes spatial correlations into the dynamical mean-field theory. A nonzero second-neighbor transfer yields a first-order Mott transition at finite temperatures ending at a critical point.
