Journal ArticleDOI
Nonequilibrium dynamical mean-field theory and its applications
TL;DR: In this paper, the authors discuss the nonequilibrium extension of the dynamical mean field theory (DMFT), which treats quantum fluctuations in the time domain and works directly in the thermodynamic limit.
Journal ArticleDOI
Thermalization after an interaction quench in the Hubbard model.
TL;DR: This work uses nonequilibrium dynamical mean-field theory to study the time evolution of the fermionic Hubbard model after an interaction quench and indicates a dynamical phase transition which should be observable in experiments on trapped fermionics atoms.
Journal ArticleDOI
Generalized Gibbs ensemble prediction of prethermalization plateaus and their relation to nonthermal steady states in integrable systems
TL;DR: In this paper, it was shown that the relaxation behaviors of integrable and nearly-integrable systems are continuously connected and described by the same statistical theory, and that prethermalization plateaus are under certain conditions correctly predicted by generalized Gibbs ensembles.
Journal ArticleDOI
Ultrafast and reversible control of the exchange interaction in Mott insulators
TL;DR: It is demonstrated that time-periodic modulation of the electronic structure by electric fields can be used to reversibly control Jex on ultrafast timescales in extended antiferromagnetic Mott insulators.
Journal ArticleDOI
Nonthermal steady states after an interaction quench in the Falicov-Kimball model.
Martin Eckstein,Marcus Kollar +1 more
TL;DR: The Falicov-Kimball model after a sudden change of its interaction parameter is presented using nonequilibrium dynamical mean-field theory and the system relaxes to a nonthermal steady state on time scales on the order of variant Planck's over 2pi/bandwidth.
