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…

Entanglement of low-energy excitations in Conformal Field Theory
Francisco Castilho Alcaraz, Miguel Ibanez Berganza, German Sierra
In a quantum critical chain, the scaling regime of the energy and momentum of the ground state and low lying excitations are described by conformal field theory (CFT). The same hol…
