Compressible Ferrimagnetism in the depleted Periodic Anderson Model
N. C. Costa, M. V. Araújo, J. P. Lima +3
Tight-binding Hamiltonians with single and multiple orbitals exhibit an intriguing array of magnetic phase transitions. In most cases the spin ordered phases are insulating, while…
Quantum transitions of the XY model with long-range interactions on the inhomogenous periodic chain
J. P. De Lima, L. L. Goncalves
The isotropic XY model in a transverse field, with uniform long-range interactions among the transverse components of the spins, on the inhomogeneous periodic chain, is s…
The anisotropic XY model on the inhomogeneous periodic chain
J. P. de Lima, L. L. Goncalves, T. F. A. Alves
The static and dynamic properties of the anisotropic XY-model on the inhomogeneous periodic chain, composed of cells with different exchange interactions and magn…
The isotropic XY model on the inhomogeneous periodic chain
J. P de Lima, T. F. A. Alves, L. L. Goncalves
The static and dynamic properties of the isotropic XY-model on the inhomogeneous periodic chain, composed of \emph{N} segments with \emph{n} different exchange interactio…
