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…

Modular Hamiltonian for (holographic) excited states
Raúl Arias, Marcelo Botta-Cantcheff, Pedro J. Martinez +1
In this work we study the Tomita-Takesaki construction for a family of excited states that, in a strongly coupled CFT - at large -, correspond to coherent states in an asymptoti…
