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…
Detecting superconductivity out-of-equilibrium
Sebastian Paeckel, Benedikt Fauseweh, Alexander Osterkorn +3
Recent pump-probe experiments on underdoped cuprates and similar systems suggest the existence of a transient superconducting state above . This poses the question ho…
Time-evolution methods for matrix-product states
Sebastian Paeckel, Thomas Köhler, Andreas Swoboda +3
Matrix-product states have become the de facto standard for the representation of one-dimensional quantum many body states. During the last few years, numerous new methods have bee…
Formation of Spatial Patterns by Spin-selective Excitations of Interacting Fermions
Thomas Köhler, Sebastian Paeckel, Constantin Meyer +1
We describe the formation of charge- and spin-density patterns induced by spin-selective photoexcitations of interacting fermionic systems in the presence of a microstructure. As a…
Automated construction of -invariant matrix-product operators from graph representations
Sebastian Paeckel, Thomas Köhler, Salvatore R. Manmana
We present an algorithmic construction scheme for matrix-product-operator (MPO) representations of arbitrary -invariant operators whenever there is an expression of the local…
