Boundary quenches in (1+1)-dimensional conformal field theory
Michele Fossati, Colin Rylands, Eytan Grosfeld +2
We investigate a class of local quantum quenches in which the conformal boundary condition of a (1+1)-dimensional conformal field theory is abruptly changed. We derive a remarkably…
Entanglement asymmetry for higher and noninvertible symmetries
Francesco Benini, Pasquale Calabrese, Michele Fossati +2
Entanglement asymmetry is an observable in quantum systems, constructed using quantum-information methods, suited to detecting symmetry breaking in states -- possibly out of equili…
Entanglement asymmetry in CFT with boundary symmetry breaking
Michele Fossati, Colin Rylands, Pasquale Calabrese
We examine the behavior of the entanglement asymmetry in the ground state of a (1+1)-dimensional conformal field theory with a boundary condition that explicitly breaks a bulk symm…
Entanglement Hamiltonian in the non-Hermitian SSH model
Federico Rottoli, Michele Fossati, Pasquale Calabrese
Entanglement Hamiltonians provide the most comprehensive characterisation of entanglement in extended quantum systems. A key result in unitary quantum field theories is the Bisogna…
Entanglement asymmetry in CFT and its relation to non-topological defects
Michele Fossati, Filiberto Ares, Jerome Dubail +1
The entanglement asymmetry is an information based observable that quantifies the degree of symmetry breaking in a region of an extended quantum system. We investigate this measure…
Symmetry-resolved entanglement in critical non-Hermitian systems
Michele Fossati, Filiberto Ares, Pasquale Calabrese
The study of entanglement in the symmetry sectors of a theory has recently attracted a lot of attention since it provides better understanding of some aspects of quantum many-body…
