Correlation and entanglement dynamics of free fermions in disguise
Dávid Szász-Schagrin, Pablo Bayona-Pena, Lorenzo Piroli +1
We study the nonequilibrium dynamics following a quantum quench in spin chains that can be solved via a mapping to free fermions in disguise. These models feature an exponential de…

Generalized hydrodynamics of free fermions under extensive-charge monitoring
Pablo Bayona-Pena, Michele Mazzoni, Lorenzo Piroli
We study transport dynamics of free fermions subject to the external monitoring of a conserved charge over an extensive region. Focusing on bipartition protocols, we consider monit…

Entanglement Spectrum Dynamics as a Probe for Non-Hermitian Bulk-Boundary Correspondence in Systems with Periodic Boundaries
Pablo Bayona-Pena, Ryo Hanai, Takashi Mori +1
It has recently been established that open quantum systems may exhibit a strong spectral sensitivity to boundary conditions, known as the non-Hermitian/Liouvillian skin effect (NHS…
