Entanglement in the Quantum Spherical Model -- a Review
Sascha Wald, Raul Arias, Vincenzo Alba
We review some recent results on entanglement in the Quantum Spherical Model (QSM). The focus lays on the physical results rather than the mathematical details. Specifically, we st…
Entanglement gap in 1D long-range quantum spherical models
Sascha Wald, Raul Arias, Vincenzo Alba
We investigate the finite-size scaling of the entanglement gap in the one dimensional long-range quantum spherical model (QSM). We focus on the weak long-range QSM, for which the t…
Entanglement dynamics of a hard-core quantum gas during a Joule expansion
Filiberto Ares, Stefano Scopa, Sascha Wald
We study the entanglement dynamics of a one-dimensional hard-core quantum gas initially confined in a box of size with saturated density . The gas is suddenly released int…
Non-equilibrium dynamics of the open quantum -model with non-Markovian noise: exact results
Sascha Wald, Malte Henkel, Andrea Gambassi
The collective and purely relaxational dynamics of quantum many-body systems after a quench at temperature , from a disordered state to various phases is studied through the e…
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…
From classical to quantum walks with stochastic resetting on networks
Sascha Wald, Lucas Böttcher
Random walks are fundamental models of stochastic processes with applications in various fields including physics, biology, and computer science. We study classical and quantum ran…
