Finite-size corrections of the Entanglement Entropy of critical quantum chains
J. C. Xavier, F. C. Alcaraz
Using the density matrix renormalization group, we calculated the finite-size corrections of the entanglement -Renyi entropy of a single interval for several critical quantum ch…

Precise Determination of Quantum Critical Points by the Violation of the Entropic Area Law
J. C. Xavier, F. C. Alcaraz
Finite-size scaling analysis turns out to be a powerful tool to calculate the phase diagram as well as the critical properties of two dimensional classical statistical mechanics mo…

Renyi Entropy and Parity Oscillations of the Anisotropic Spin-s Heisenberg Chains in a Magnetic Field
J. C. Xavier, F. C. Alcaraz
Using the density matrix renormalization group, we investigate the Renyi entropy of the anisotropic spin-s Heisenberg chains in a z-magnetic field. We considered the half-odd integ…
