Transient superconductivity in three-dimensional Hubbard systems by combining matrix product states and self-consistent mean-field theory
Svenja Marten, Gunnar Bollmark, Thomas Köhler +2
We combine matrix-product state (MPS) and Mean-Field (MF) methods to model the real-time evolution of a three-dimensional (3D) extended Hubbard system formed from one-dimensional (…
Solving 2D and 3D lattice models of correlated fermions -- combining matrix product states with mean field theory
Gunnar Bollmark, Thomas Köhler, Lorenzo Pizzino +6
Correlated electron states are at the root of many important phenomena including unconventional superconductivity (USC), where electron-pairing arises from repulsive interactions.…
Symmetry-protected Bose-Einstein condensation of interacting hardcore Bosons
R. H. Wilke, T. Köhler, F. A. Palm +1
We introduce a mechanism stabilizing a one-dimensional quantum many-body phase, characterized by a certain wave vector , from a -modulated coupling to a center site, via…
Finite-Temperature Dynamics and Thermal Intraband Magnon Scattering in Haldane Spin-One Chains
Jonas Becker, Thomas Köhler, Alexander C. Tiegel +3
The antiferromagnetic spin-one chain is considerably one of the most fundamental quantum many-body systems, with symmetry protected topological order in the ground state. Here, we…
Relaxation of photoexcitations in polaron-induced magnetic microstructures
Thomas Köhler, Sangeeta Rajpurohit, Ole Schumann +7
We investigate the evolution of a photoexcitation in correlated materials over a wide range of time scales. The system studied is a one-dimensional model of a manganite with correl…
