Landau Theory of the Finite Temperature Mott Transition
arXiv:cond-mat/0003016 · doi:10.1103/PhysRevLett.84.5180
Abstract
In the context of the dynamical mean-field theory of the Hubbard model, we identify microscopically an order parameter for the finite temperature Mott endpoint. We derive a Landau functional of the order parameter. We then use the order parameter theory to elucidate the singular behavior of various physical quantities which are experimentally accessible.
