The non-stabilizerness of fermionic Gaussian states
Mario Collura, Jacopo De Nardis, Vincenzo Alba +1
We introduce an efficient method to quantify nonstabilizerness in fermionic Gaussian states, overcoming the long-standing challenge posed by their extensive entanglement. Using a p…

More on the Operator Space Entanglement (OSE): Rényi OSE, revivals, and integrability breaking
Vincenzo Alba
We investigate the dynamics of the Rényi Operator Space Entanglement () entropies across several one-dimensional integrable and chaotic models. As a paradigmatic integr…

Free fermions with dephasing and boundary driving: Bethe Ansatz results
Vincenzo Alba
By employing the Lindblad equation, we derive the evolution of the two-point correlator for a free-fermion chain of length subject to bulk dephasing and boundary losses. We use…
