Transport Properties of a One-Dimensional Two-Component Quantum Liquid with Hyperbolic Interactions
arXiv:cond-mat/9403015 · doi:10.1103/PhysRevB.50.15389
Abstract
We present an investigation of the sinh-cosh (SC) interaction model with twisted boundary conditions. We argue that, when unlike particles repel, the SC model may be usefully viewed as a Heisenberg-Ising fluid with moving Heisenberg-Ising spins. We derive the Luttinger liquid relation for the stiffness and the susceptibility, both from conformal arguments, and directly from the integral equations. Finally, we investigate the opening and closing of the ground state gaps for both SC and Heisenberg-Ising models, as the interaction strength is varied.
