Non-equilibrium entanglement asymmetry for discrete groups: the example of the XY spin chain
Entanglement asymmetry is a novel quantity that, using entanglement methods, measures

Dynamics of charge-imbalance-resolved entanglement negativity after a quench in a free-fermion model
The presence of a global internal symmetry in a quantum many-body system is reflected in
the fact that the entanglement between its subparts is endowed with an internal structure …

Reflected entropy and computable cross-norm negativity: Free theories and symmetry resolution
We investigate a separability criterion based on the computable cross-norm (CCNR), and a
related quantity called the CCNR negativity. We introduce a reflected version of the CCNR …

Negative tripartite mutual information after quantum quenches in integrable systems
F Caceffo, V Alba - Physical Review B, 2023 - APS
We build the quasiparticle picture for the tripartite mutual information (TMI) after quantum
quenches in spin chains that can be mapped onto free-fermion theories. A nonzero TMI …
