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…
