Fragmented superconductivity in the Hubbard model as solitons in Ginzburg-Landau theory
Niccolò Baldelli, Hannes Karlsson, Benedikt Kloss +2
The phenomena of superconductivity and charge density waves are observed in close vicinity in many strongly correlated materials. Increasing evidence from experiments and numerical…
Equilibrium Quantum Impurity Problems via Matrix Product State Encoding of the Retarded Action
Benedikt Kloss, Julian Thoenniss, Michael Sonner +6
In the dimensional imaginary-time path integral formulation of quantum impurity problems, the retarded action encodes the hybridization of the impurity with the bath. In this…
Non-equilibrium correlation dynamics in the one-dimensional Fermi-Hubbard model: A testbed for the two-particle reduced density matrix theory
Stefan Donsa, Fabian Lackner, Joachim Burgdörfer +4
We explore the non-equilibrium dynamics of a one-dimensional Fermi-Hubbard system as a sensitive testbed for the capabilities of the time-dependent two-particle reduced density mat…
Absence of localization in interacting spin chains with a discrete symmetry
Benedikt Kloss, Jad C. Halimeh, Achilleas Lazarides +1
We prove that spin chains symmetric under a combination of mirror and spin-flip symmetries and with a nondegenerate spectrum show finite spin transport at zero total magnetization…
Time Evolution of ML-MCTDH Wavefunctions II: Application of the Projector Splitting Integrator
Lachlan P. Lindoy, Benedikt Kloss, David R. Reichman
The multi-layer multiconfiguration time-dependent Hartree (ML-MCTDH) approach suffers from numerical instabilities whenever the wavefunction is weakly entangled. These instabilitie…
Time Evolution of ML-MCTDH Wavefunctions I: Gauge Conditions, Basis Functions, and Singularities
Lachlan P. Lindoy, Benedikt Kloss, David R. Reichman
We derive a family of equations of motion (EOMs) for evolving multi-layer multiconfiguration time-dependent Hartree (ML-MCTDH) wavefunctions that, unlike the standard ML-MCTDH EOMs…
