Phase diagram of the asymmetric tetrahedral Ising-Heisenberg chain
J. S. Valverde, Onofre Rojas, S. M. de Souza.
The asymmetric tetrahedron is composed by all edges of tetrahedron represented by Ising interaction except one, which has a Heisenberg type interaction. This asymmetric tetrahedron…

A set of exactly solvable Ising models with half-odd-integer spin
Onofre Rojas, S. M. de Souza
We present a set of exactly solvable Ising models, with half-odd-integer spin-S on a square-type lattice including a quartic interaction term in the Hamiltonian. The particular pro…
