Journal ArticleDOI
Parity-time symmetry-breaking mechanism of dynamic Mott transitions in dissipative systems
TL;DR: In this article, the authors describe the critical behavior of the electric field-driven (dynamic) Mott insulator-to-metal transitions in dissipative Fermi and Bose systems in terms of non-Hermitian Hamiltonians invariant under simultaneous parity and time-reversal operations.
Journal ArticleDOI
Scaling universality at the dynamic vortex Mott transition

TL;DR: In this article, the authors report the critical behavior of the vortex system as it crosses the DMT line, driven by either current or temperature and find universal scaling with respect to both, expressed by the same scaling function.
Journal ArticleDOI
Realization of a scenario with two relaxation rates in the Hubbard Falicov-Kimball model
TL;DR: In this article, the authors explore the emergence of two relaxation rates in the Hubbard-Falicov-Kimball model (HFKM) using the dynamical mean-field theory (DMFT).
Journal ArticleDOI
Local moment approach as a quantum impurity solver for the Hubbard model
TL;DR: In this article, the filling-interaction phase diagram of the single band Hubbard model at zero temperature is presented, which can be generalized to any particle filling and can be extended to finite temperature.
Journal Article
Transport and spectra in the half--filled Hubbard model
TL;DR: An improved numerical implementation of the iterated perturbation theory for use as an impurity solver for lattice models within dynamical mean field theory (DMFT) is presented in this article.
