A Tensor Train Continuous Time Solver for Quantum Impurity Models
A. Erpenbeck, W. -T. Lin, T. Blommel +8
The simulation of strongly correlated quantum impurity models is a significant challenge in modern condensed matter physics that has multiple important applications. Thus far, the…
Quantum Monte Carlo in the steady-state
André Erpenbeck, Emanuel Gull, Guy Cohen
We present a numerically exact steady-state inchworm Monte Carlo method for nonequilibrium quantum impurity models. Rather than propagating an initial state to long times, the meth…
Interaction expansion inchworm Monte Carlo solver for lattice and impurity models
Jia Li, Yang Yu, Emanuel Gull +1
Multi-orbital quantum impurity models with general interaction and hybridization terms appear in a wide range of applications including embedding, quantum transport, and nanoscienc…
The Kondo Cloud in a 1D Nanowire
Joseph Kleinhenz, Igor Krivenko, Guy Cohen +1
A recent experiment [Nature 579, 210--213 (2020)] probed the extent of the Kondo cloud in 1D by measuring the effect of electrostatic perturbations applied a distance away from…
Dynamic Control of Nonequilibrium Metal-Insulator Transitions
Joseph Kleinhenz, Igor Krivenko, Guy Cohen +1
We demonstrate a first order metal-insulator phase transition in the repulsive, fully frustrated, single-band Hubbard model as a function of the coupling to a fermion bath. Time de…
Correlated nonequilibrium steady states without energy flux
Hristiana Atanasova, Alexander I. Lichtenstein, Guy Cohen
Floquet engineering of closed quantum systems can lead to the formation of long-lived prethermal states that, in general, eventually thermalize to infinite temperature. Coupling th…
