Diagnosing phase transitions through time-scale entanglement
Stefan Rohshap, Hirone Ishida, Frederic Bippus +5
Spatial entanglement of quantum states has become a central paradigm of many-body physics. Here, we unearth a fundamentally different form of entanglement, the entanglement between…
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-…
