Equipartition of the Entanglement Entropy
J. C. Xavier, F. C. Alcaraz, G. Sierra
The entanglement in a quantum system that possess an internal symmetry, characterized by the Sz-magnetization or U(1)-charge, is distributed among different sectors. The aim of thi…

Finite Size Corrections to Entanglement in Quantum Critical Systems
F. C. Alcaraz, M. S. Sarandy
We analyze the finite size corrections to entanglement in quantum critical systems. By using conformal symmetry and density functional theory, we discuss the structure of the finit…

The Wave Functions for the Free-Fermion Part of the Spectrum of the Quantum Spin Models
F. C. Alcaraz, Yu. G. Stroganov
We conjecture that the free-fermion part of the eigenspectrum observed recently for the Perk-Schultz spin chain Hamiltonian in a finite lattice with …
