Modulated phases and devil's staircases in a layered mean-field version of the ANNNI model
E. S. Nascimento, J. P. de Lima, S. R. Salinas
We investigate the phase diagram of a spin- Ising model on a cubic lattice, with competing interactions between nearest and next-nearest neighbors along an axial direction, an…
Quantum phase transitions of the extended isotropic XY model with long-range interactions
F. G. Ribeiro, J. P. de Lima, L. L. Goncalves
The one-dimensional extended isotropic XY model (s=1/2) in a transverse field with uniform long-range interactions among the \textit{z} components of the spin is considered. The mo…
Critical properties of the XXZ model with long-range interactions on the double chain
J. P. de Lima, L. L. Goncalves
The model in a transverse field on a double chain with a uniform long-range interaction among the components of the spins is considered. The nearest-neighbour…
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 XY model on the one-dimensional superlattice: static properties
J. P. de Lima, L. L. Goncalves
The XY model (s=1/2) on the one-dimensional alternating superlattice (closed chain) is solved exactly by using a generalized Jordan-Wigner transformation and the Green function met…
