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…
Probing RG flows, symmetry resolution and quench dynamics through the capacity of entanglement
Raúl Arias, Giuseppe Di Giulio, Esko Keski-Vakkuri +1
We compare the capacity of entanglement with the entanglement entropy by considering various aspects of these quantities for free bosonic and fermionic models in one spatial dimens…
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…
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…
Rényi entropy and subsystem distances in finite size and thermal states in critical XY chains
Raúl Arias, Jiaju Zhang
We study the Rényi entropy and subsystem distances on one interval for the finite size and thermal states in the critical XY chains, focusing on the critical Ising chain and XX cha…
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…
