The Effect of a Long-Range Correlated-Hopping Interaction on Bariev Spin Chains

The Effect of a Long-Range Correlated-Hopping Interaction on Bariev Spin Chains

We introduce a long-range particle and spin interaction into the standard Bariev model and show that this interaction is equivalent to a phase shift in the kinetic term of the Hamiltonian. When the particles circle around the chain and across the boundary, the accumulated phase shift acts as a twist...
