Spectrum and transition rates of the XX chain analyzed via Bethe ansatz

Daniel Biegel, Michael Karbach, Gerhard Muller +1

As part of a study that investigates the dynamics of the s=1/2 XXZ model in the planar regime |Delta|<1, we discuss the singular nature of the Bethe ansatz equations for the case D…
