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…

In and out of equilibrium quantum metrology with mean-field quantum criticality
Sascha Wald, Saulo V. Moreira, Fernando L. Semião
We study the influence that collective transition phenomena have on quantum metrological protocols. The single spherical quantum spin (SQS) serves as stereotypical toy model that a…
