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…
Entanglement in the pseudogap regime of cuprate superconductors
Frederic Bippus, Juraj Krsnik, Motoharu Kitatani +4
We find a strongly enhanced entanglement within the pseudogap regime of the Hubbard model. This entanglement is estimated from the quantum Fisher information and, avoiding the ill-…
Pseudo-Majorana functional renormalization for frustrated XXZ spin-1/2 models with field or magnetization along the spin-Z direction at finite temperature
Frederic Bippus, Benedikt Schneider, Björn Sbierski
The numerical study of high-dimensional frustrated quantum magnets remains a challenging problem. Here we present an extension of the pseudo-Majorana functional renormalization gro…
