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…

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…
