Operator-Space Entanglement Entropy in Random Fermionic Gaussian Dynamics
Pablo Bayona-Pena, Elena Gramellini, Lorenzo Piroli
We study the von Neumann operator-space entanglement entropy (OSEE) of initial product operators evolved under random gaussian dynamics, as modeled by a Brownian SYK model. By…
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…
An asymmetry lower bound on fermionic non-Gaussianity
Filiberto Ares, Michele Mazzoni, Sara Murciano +3
Fermionic Gaussian states are a fundamental tool in many-body physics, faithfully representing non-interacting quantum systems and allowing for efficient numerical simulations. Giv…
