Quantum many-body scars in random unitary circuits
Luca Capizzi, Benoît Ferté
Quantum many-body scars are rare exceptions to thermalization: they sustain non-thermal stationary states without the protection of any local conservation law, and are generally ex…
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…
Breaking global symmetries with locality-preserving operations
Michele Mazzoni, Luca Capizzi, Lorenzo Piroli
In the general framework of quantum resource theories, one typically only distinguishes between operations that can or cannot generate the resource of interest. In many-body settin…
Entanglement content of kink excitations
Luca Capizzi, Michele Mazzoni
Quantum one-dimensional systems in their ordered phase admit kinks as elementary excitations above their symmetry-broken vacua. While the scattering properties of the kinks resembl…
Energy-filtered quantum states and the emergence of non-local correlations
Gianluca Morettini, Luca Capizzi, Maurizio Fagotti +1
Energy-filtered quantum states are promising candidates for efficiently simulating thermal states. We explore a protocol designed to transition a product state into an eigenstate l…
Thermal entanglement in conformal junctions
Luca Capizzi, Andrei Rotaru
We consider a quantum junction described by a 1+1-dimensional boundary conformal field theory (BCFT). Our analysis focuses on correlations emerging at finite temperature, achieved…
A universal formula for the entanglement asymmetry of matrix product states
Luca Capizzi, Vittorio Vitale
Symmetry breaking is a fundamental concept in understanding quantum phases of matter, studied so far mostly through the lens of local order parameters. Recently, a new entanglement…
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…
Symmetry Resolved Entanglement of Excited States in Quantum Field Theory III: Bosonic and Fermionic Negativity
Luca Capizzi, Michele Mazzoni, Olalla A. Castro-Alvaredo
In two recent works, we studied the symmetry resolved Rényi entropies of quasi-particle excited states in quantum field theory. We found that the entropies display many model-indep…
Full counting statistics and symmetry resolved entanglement for free conformal theories with interface defects
Luca Capizzi, Sara Murciano, Pasquale Calabrese
We consider the ground state of two species of one-dimensional critical free theories coupled together via a conformal interface. They have an internal global symmetry and w…
Boundary Symmetry Breaking in CFT and the String Order Parameter
Riccarda Bonsignori, Luca Capizzi, Pantelis Panopoulos
We consider the ground state of a one-dimensional critical quantum system carrying a global symmetry in the bulk, which is explicitly broken by its boundary conditions. We probe th…
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…
