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, Gergő Roósz +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
Gergő Roósz
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…
Entanglement scaling in fermion chains with a localization-delocalization transition and inhomogeneous modulations
Gergő Roósz, Zoltán Zimborás, Róbert Juhász
We study the scaling of logarithmic negativity between adjacent subsystems in critical fermion chains with various inhomogeneous modulations through numerically calculating its rec…
