Non-equilibrium entanglement asymmetry for discrete groups: the example of the XY spin chain
Journal of Statistical Mechanics: Theory and Experiment, 2024•iopscience.iop.org
Entanglement asymmetry is a novel quantity that, using entanglement methods, measures
how much a symmetry is broken in a part of an extended quantum system. So far, it has only
been used to characterise the breaking of continuous Abelian symmetries. In this paper, we
extend the concept to cyclic $\mathbb {Z} _N$
