Real-time non-adiabatic dynamics in the one-dimensional Holstein model: Trajectory-based vs exact methods
Michael ten Brink, Stefan Gräber, Miroslav Hopjan +4
We benchmark a set of quantum-chemistry methods, including multitrajectory Ehrenfest, fewest-switches surface-hopping, and multiconfigurational-Ehrenfest dynamics, against exact qu…
Comparative Study of State-of-the-Art Matrix-Product-State Methods for Lattice Models with Large Local Hilbert Spaces
Jan Stolpp, Thomas Köhler, Salvatore R. Manmana +3
Lattice models consisting of high-dimensional local degrees of freedom without global particle-number conservation constitute an important problem class in the field of strongly co…
Efficient and Flexible Approach to Simulate Low-Dimensional Quantum Lattice Models with Large Local Hilbert Spaces
Thomas Köhler, Jan Stolpp, Sebastian Paeckel
Quantum lattice models with large local Hilbert spaces emerge across various fields in quantum many-body physics. Problems such as the interplay between fermions and phonons, the B…
Charge-density-wave melting in the one-dimensional Holstein model
Jan Stolpp, Jacek Herbrych, Florian Dorfner +2
We study the Holstein model of spinless fermions, which at half-filling exhibits a quantum phase transition from a metallic Tomonaga-Luttinger liquid phase to an insulating charge-…
Eigenstate thermalization and quantum chaos in the Holstein polaron model
David Jansen, Jan Stolpp, Lev Vidmar +1
The eigenstate thermalization hypothesis (ETH) is a successful theory that provides sufficient criteria for ergodicity in quantum many-body systems. Most studies were carried out f…
Large magnetic thermal conductivity induced by frustration in low-dimensional quantum magnets
Jan Stolpp, Shang-Shun Zhang, Fabian Heidrich-Meisner +1
We study the magnetic field-dependence of the thermal conductivity due to magnetic excitations in frustrated spin-1/2 Heisenberg chains. Near the saturation field, the system is de…
