Field-driven Mott gap collapse and resistive switch in correlated insulators

G Mazza, A Amaricci, M Capone, M Fabrizio - Physical review letters, 2016 - APS
Mott insulators are “unsuccessful metals” in which Coulomb repulsion prevents charge
conduction despite a metal-like concentration of conduction electrons. The possibility to …

Nonequilibrium steady states of electric field driven Mott insulators

Y Murakami, P Werner - Physical Review B, 2018 - APS
We present a systematic study of the nonequilibrium steady states (NESS) in Mott insulators
driven by dc or ac electric fields, based on the Floquet dynamical mean-field theory. The …

Electric-field-driven resistive switching in the dissipative Hubbard model

J Li, C Aron, G Kotliar, JE Han - Physical review letters, 2015 - APS
We study how strongly correlated electrons on a dissipative lattice evolve out of equilibrium

Correlated Mott insulators in strong electric fields: Role of phonons in heat dissipation

TM Mazzocchi, P Gazzaneo, J Lotze, E Arrigoni - Physical Review B, 2022 - APS
We study the spectral and transport properties of a Mott insulator driven by a static electric
field into a nonequilibrium steady state. For the dissipation, we consider two mechanisms …

Dynamical mean-field theory, density-matrix embedding theory, and rotationally invariant slave bosons: A unified perspective

T Ayral, TH Lee, G Kotliar - Physical Review B, 2017 - APS
We present a unified perspective on dynamical mean-field theory (DMFT), density-matrix
embedding theory (DMET), and rotationally invariant slave bosons (RISB). We show that …

Electrically driven insulator-to-metal transition in a correlated insulator: Electronic mechanism and thermal description

MI Díaz, JE Han, C Aron - Physical Review B, 2023 - APS
Motivated by the resistive switchings in transition-metal oxides (TMOs) induced by a voltage
bias, we study the far-from-equilibrium dynamics of an electric-field-driven strongly …
