Modular invariance in the gapped XYZ spin-1/2 chain

Modular invariance in the gapped XYZ spin-1/2 chain

We show that the elliptic parametrization of the coupling constants of the quantum XYZ spin chain can be analytically extended outside of their natural domain, to cover the whole phase diagram of the model, which is composed of 12 adjacent regions, related to one another by a spin rotation. This ext...
