Emergence of spin entanglement with the pseudogap onset in the Fermi-Hubbard model
Frederic Bippus, Thomas Chalopin, Gabriele Bellomia +6
Despite decades of intense theoretical and experimental investigation, the two-dimensional Fermi-Hubbard model still resists a complete microscopic understanding. Conventional appr…

Two-site entanglement in the two-dimensional Hubbard model
Frederic Bippus, Anna Kauch, GergŠRoósz +3
The study of entanglement in strongly correlated electron systems typically requires knowledge of the reduced density matrix. Here, we apply the parquet dynamical vertex approximat…

Lindbladian way for the relaxation time approximation, application to Kibble-Zurek processes due to environment temperature quench, and to Lindbladian perturbation theory
GergŠRoósz
In the present paper, a global Lindbladian ansatz is constructed which leads to thermalization at temperature to the Gibs state of the investigated system. This ansatz connects…
