Essential singularity in the Renyi entanglement entropy of the one-dimensional XYZ spin-1/2 chain
Elisa Ercolessi, Stefano Evangelisti, Fabio Franchini +1
We study the Renyi entropy of the one-dimensional XYZ spin-1/2 chain in the entirety of its phase diagram. The model has several quantum critical lines corresponding to rotated XXZ…

Entanglement Spectrum for the XY Model in One Dimension
F. Franchini, A. R. Its, V. E. Korepin +1
We consider the reduced density matrix of a large block of consecutive spins in the ground states of the XY spin chain on an infinite lattice. We derive the spectrum of the density…
