Static and dynamic properties of the XXZ chain with long-range interactions
L. L. Gonçalves, L. P. S. Coutinho, J. P. de Lima
The one-dimensional XXZ model (s=1/2) in a transverse field, with uniform long-range interactions among the transverse components of the spins, is studied. The model is exactly sol…

The one-dimensional XXZ model with long-range interactions
L. L. Goncalves, A. P. Vieira, L. P. S. Coutinho
The one-dimensional XXZ model (s=1/2, N sites) with uniform long-range interactions among the transverse components of the spins is considered. The Hamiltonian of the model is expl…
