Scaling properties of a spatial one-particle density-matrix entropy in many-body localized systems
Miroslav Hopjan, Fabian Heidrich-Meisner, Vincenzo Alba
We investigate a spatial subsystem entropy extracted from the one-particle density matrix (OPDM) in one-dimensional disordered interacting fermions that host a many-body localized…
Entanglement gap, corners, and symmetry breaking
Vincenzo Alba
We investigate the finite-size scaling of the lowest entanglement gap in the ordered phase of the two-dimensional quantum spherical model (QSM). The entanglement gap decays as…
Closure of the entanglement gap at quantum criticality: The case of the Quantum Spherical Model
Sascha Wald, Raul Arias, Vincenzo Alba
The study of entanglement spectra is a powerful tool to detect or elucidate universal behaviour in quantum many-body systems. We investigate the scaling of the entanglement (or Sch…
Diffusion and operator entanglement spreading
Vincenzo Alba
Understanding the spreading of the operator space entanglement entropy () is key in order to explore out-of-equilibrium quantum many-body systems. Here we argue that for inte…
Entanglement equipartition in critical random spin chains
Xhek Turkeshi, Paola Ruggiero, Vincenzo Alba +1
The reduced density matrix of many-body systems possessing an additive conserved quantity can be decomposed in orthogonal sectors which can be independently analyzed. Recently, the…
Entanglement revivals as a probe of scrambling in finite quantum systems
Ranjan Modak, Vincenzo Alba, Pasquale Calabrese
The entanglement evolution after a quantum quench became one of the tools to distinguish integrable versus chaotic (non-integrable) quantum many-body dynamics. Following this line…
