symmetry of XX spin chains

Nicolas Crampé, Rafael I. Nepomechie, Luc Vinet +1

We show that, after suitably adjusting a uniform transverse magnetic field, the generic inhomogeneous open XX spin chain has a two-fold degeneracy, and an exact symmetry wh…

Entanglement of Inhomogeneous Free Bosons and Orthogonal Polynomials

Pierre-Antoine Bernard, Rafael I. Nepomechie, Gilles Parez +3

In this paper, we investigate the ground-state entanglement entropy in inhomogeneous free-boson models in one spatial dimension. We develop a powerful method to extract the leading…
