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…
