Permutation operators, entanglement entropy, and the XXZ spin chain in the limit Δ-> -1
Permutation operators entanglement entropy the XXZ spin chain
2010/12/24
In this paper we develop a new approach to the investigation of the bi-partite entanglement entropy in integrable quantum spin chains. Our method employs the well-known replica trick, thus taking a re...
Permutation Orbifold of N=2 Supersymmetric Minimal Models
Permutation Orbifold N=2 Supersymmetric Minimal Models
2010/12/23
In this paper we apply the previously derived formalism of permutation orbifold conformal field theories to N=2 supersymmetric minimal models. By interchanging extensions and permutations of the fact...
