Correlation Length and Unusual Corrections to the Entanglement Entropy
Elisa Ercolessi, Stefano Evangelisti, Fabio Franchini +1
We study analytically the corrections to the leading terms in the Renyi entropy of a massive lattice theory, showing significant deviations from naive expectations. In particular,…

Exact entanglement entropy of the XYZ model and its sine-Gordon limit
Elisa Ercolessi, Stefano Evangelisti, Francesco Ravanini
We obtain the exact expression for the Von Neumann entropy for an infinite bipartition of the XYZ model, by connecting its reduced density matrix to the corner transfer matrix of t…
