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…
Detecting a long lived false vacuum with quantum quenches
Gianluca Lagnese, Federica Maria Surace, Sid Morampudi +1
Distinguishing whether a system supports alternate low-energy (locally stable) states -- stable (true vacuum) versus metastable (false vacuum) -- by direct observation can be diffi…
Growth of Rényi Entropies in Interacting Integrable Models and the Breakdown of the Quasiparticle Picture
Bruno Bertini, Katja Klobas, Vincenzo Alba +2
Rényi entropies are conceptually valuable and experimentally relevant generalisations of the celebrated von Neumann entanglement entropy. After a quantum quench in a clean quantum…
Entanglement dynamics of thermofield double states in integrable models
Gianluca Lagnese, Pasquale Calabrese, Lorenzo Piroli
We study the entanglement dynamics of thermofield double (TFD) states in integrable spin chains and quantum field theories. We show that, for a natural choice of the Hamiltonian ei…
Quenches and confinement in a Heisenberg-Ising spin ladder
Gianluca Lagnese, Federica Maria Surace, Márton Kormos +1
We consider the quantum quench dynamics of a Heisenberg-Ising spin ladder which is an archetypal model in which confinement of elementary excitations is triggered by internal inter…
False vacuum decay in quantum spin chains
Gianluca Lagnese, Federica Maria Surace, Márton Kormos +1
The false vacuum decay has been a central theme in physics for half a century with applications to cosmology and to the theory of fundamental interactions. This fascinating phenome…
Confinement in the spectrum of a Heisenberg-Ising spin ladder
Gianluca Lagnese, Federica Maria Surace, Márton Kormos +1
The Heisenberg-Ising spin ladder is one of the few short-range models showing confinement of elementary excitations without the need of an external field, neither transverse nor lo…
