Powerful method to evaluate the mass gaps of free-particle quantum critical systems
Francisco C. Alcaraz, José A. Hoyos, Rodrigo A. Pimenta
We present a numerical method for the evaluation of the mass gap, and the low-lying energy gaps, of a large family of free-fermionic and free-parafermionic quantum chains. The meth…

Slavnov and Gaudin-Korepin Formulas for Models without Symmetry: the Twisted XXX Chain
Samuel Belliard, Rodrigo A. Pimenta
We consider the XXX spin- Heisenberg chain on the circle with an arbitrary twist. We characterize its spectral problem using the modified algebraic Bethe anstaz and st…
