Interacting bosonic flux ladders with a synthetic dimension: Ground-state phases and quantum quench dynamics
Maximilian Buser, Claudius Hubig, Ulrich Schollwöck +2
Flux ladders constitute the minimal setup enabling a systematic understanding of the rich physics of interacting particles subjected simultaneously to strong magnetic fields and a…
Evaluation of time-dependent correlators after a local quench in iPEPS: hole motion in the t-J model
C. Hubig, A. Bohrdt, M. Knap +2
Infinite projected entangled pair states (iPEPS) provide a convenient variational description of infinite, translationally-invariant two-dimensional quantum states. However, the si…
Open quantum systems in thermal non-ergodic environments
Carlos A. Parra-Murillo, Max Bramberger, Claudius Hubig +1
The dynamics of an open system crucially depends on the correlation function of its environment, . We show that for thermal non-Harmonic environments may not decay…
Absence of superconductivity in the pure two-dimensional Hubbard model
Mingpu Qin, Chia-Min Chung, Hao Shi +5
We study the superconducting pairing correlations in the ground state of the doped Hubbard model -- in its original form without hopping beyond nearest neighbor or other perturbing…
Imaginary-time matrix product state impurity solver in a real material calculation: Spin-orbit coupling in SrRuO
Nils-Oliver Linden, Manuel Zingl, Claudius Hubig +2
Using an imaginary-time matrix-product state (MPS) based quantum impurity solver we perform a realistic dynamical mean-field theory (DMFT) calculation combined with density functio…
Gaussian time dependent variational principle for the Bose-Hubbard model
Tommaso Guaita, Lucas Hackl, Tao Shi +3
We systematically extend Bogoliubov theory beyond the mean field approximation of the Bose-Hubbard model in the superfluid phase. Our approach is based on the time dependent variat…
