Breaking of clustering and macroscopic coherence under the lens of asymmetry measures
Florent Ferro
In one-dimensional systems, spontaneous symmetry breaking (SSB) states are fragile by nature, as the injection of a non-zero energy density above the ground state is expected to re…
Kicking Quantum Fisher Information out of Equilibrium
Florent Ferro, Maurizio Fagotti
Quantum Fisher Information (QFI) is a ubiquitous quantity with applications ranging from quantum metrology and resource theories to condensed matter physics. In equilibrium local q…
Disorder-Order Interface Propagating over the Ferromagnetic Ground State in the Transverse Field Ising Chain
Vanja Marić, Florent Ferro, Maurizio Fagotti
We consider time evolution of order parameters and entanglement asymmetries in the ferromagnetic phase of the transverse-field Ising chain. One side of the system is prepared in a…
Macroscopic Quantum States and Universal Correlations in a Disorder-Order Interface Propagating over a 1D Ground State
Vanja Marić, Florent Ferro, Maurizio Fagotti
We consider translationally invariant quantum spin- chains with local interactions and a discrete symmetry that is spontaneously broken at zero temperature. We envisio…
Non-equilibrium entanglement asymmetry for discrete groups: the example of the XY spin chain
Florent Ferro, Filiberto Ares, Pasquale Calabrese
The 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…
