Neural network modeling of many-body super- and sub-radiant dynamics
Gianluca Lagnese, Laurin Brunner, Lorenzo Rossi +3
There is significant interest in exploring novel phenomena in quantum light-matter interfaces, which are driven by the combination of structured dissipation and long-range interact…
Universality of equilibration dynamics after quantum quenches
Vincenzo Alba, Sanam Azarnia, Gianluca Lagnese +1
We investigate the distribution of the eigenvalues of the reduced density matrix (entanglement spectrum) after a global quantum quench. We show that in an appropriate scaling limit…
Conserved quantities enable the quantum Mpemba effect in weakly open systems
Iris Ulčakar, Rustem Sharipov, Gianluca Lagnese +1
Observation of the quantum Mpemba effect has spurred much interest in its enabling conditions and its relation to the classical counterpart. Here, we consider weakly open many-body…
Probing false vacuum decay on a cold-atom gauge-theory quantum simulator
Zi-Hang Zhu, Ying Liu, Gianluca Lagnese +9
In the context of quantum electrodynamics, the decay of false vacuum leads to the production of electron-positron pair, a phenomenon known as the Schwinger effect. In practical exp…
