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…
The Hilbert-space structure of free fermions in disguise

Free fermions in disguise (FFD) Hamiltonians describe spin chains which can be mapped to free fermions, but not via a Jordan-Wigner transformation. Although the mapping gives acces…

Dávid Szász-Schagrin, Michele Mazzoni, Bruno Bertini +2
The characterization of ensembles of many-qubit random states and their realization via quantum circuits are crucial tasks in quantum-information theory. In this work, we study the…

We develop a general approach to compute the symmetry-resolved Rényi and von Neumann entanglement entropies (SREE) of thermodynamic macrostates in interacting integrable systems. O…
