Eigenstate thermalization and quantum chaos in the Holstein polaron model

D Jansen, J Stolpp, L Vidmar, F Heidrich-Meisner - Physical Review B, 2019 - APS
The eigenstate thermalization hypothesis (ETH) is a successful theory that provides
sufficient criteria for ergodicity in quantum many-body systems. Most studies were carried …

Theory of light-enhanced phonon-mediated superconductivity

MA Sentef, AF Kemper, A Georges, C Kollath - Physical Review B, 2016 - APS

Real-time dynamics of an impurity in an ideal Bose gas in a trap

AG Volosniev, HW Hammer, NT Zinner - Physical Review A, 2015 - APS
We investigate the behavior of a harmonically trapped system consisting of an impurity in a
dilute ideal Bose gas after the boson-impurity interaction is suddenly switched on. As a …

Interaction quench in the Holstein model: Thermalization crossover from electron-to phonon-dominated relaxation

Y Murakami, P Werner, N Tsuji, H Aoki - Physical Review B, 2015 - APS
We study the relaxation of the Holstein model after a sudden switch-on of the interaction by
means of the nonequilibrium dynamical mean field theory, with the self-consistent Migdal …

Matrix-product-state method with a dynamical local basis optimization for bosonic systems out of equilibrium
