Phase Transitions without gap closing in monitored quantum mean-field systems
Luca Capizzi, Riccardo Travaglino
We investigate the monitored dynamics of many-body quantum systems in which projective measurements of extensive operators are alternated with unitary evolution. Focusing on mean-f…
Entanglement asymmetry in the ordered phase of many-body systems: the Ising Field Theory
Luca Capizzi, Michele Mazzoni
Global symmetries of quantum many-body systems can be spontaneously broken. Whenever this mechanism happens, the ground state is degenerate and one encounters an ordered phase. In…
A hydrodynamic approach to Stark localization
Luca Capizzi, Carlo Vanoni, Pasquale Calabrese +1
When a free Fermi gas on a lattice is subject to the action of a linear potential it does not drift away, as one would naively expect, but it remains spatially localized. Here we r…
Zero-mode entanglement across a conformal defect
Luca Capizzi, Viktor Eisler
We consider a free-fermion chain with a conformal defect that features an extended zero mode, and study the entanglement properties in its mixed ground state. The zero-mode induced…
Domain wall melting across a defect
Luca Capizzi, Stefano Scopa, Federico Rottoli +1
We study the melting of a domain wall in a free-fermionic chain with a localised impurity. We find that the defect enhances quantum correlations in such a way that even the smalles…
Entanglement evolution after a global quench across a conformal defect
Luca Capizzi, Viktor Eisler
We study the evolution of entanglement after a global quench in a one-dimensional quantum system with a localized impurity. For systems described by a conformal field theory, the e…
Symmetry resolved entanglement entropy of excited states in a CFT
Luca Capizzi, Paola Ruggiero, Pasquale Calabrese
We report a throughout analysis of the entanglement entropies related to different symmetry sectors in the low-lying primary excited states of a conformal field theory (CFT) with a…
