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…
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…
Spreading of correlations in Markovian open quantum systems
Vincenzo Alba, Federico Carollo
Understanding the spreading of quantum correlations in out-of-equilibrium many-body systems is one of the major challenges in physics. For {\it isolated} systems, a hydrodynamic th…
Entanglement and classical fluctuations at finite-temperature critical points
Sascha Wald, Raul Arias, Vincenzo Alba
We investigate several entanglement-related quantities at finite-temperature criticality in the three-dimensional quantum spherical model, both as a function of temperature and…
