Existence of a New Quantum Phase in Exactly Solvable Antiferromagnetic Ising-Heisenberg Models on Planar Lattices
Michai Jascur, Jozef Strecka
In this work we deal with doubly decorated Ising-Heisenberg models on planar lattices. Applying the generalized decoration-iteration transformation we obtain exact results for the…

Influence of an Anisotropic Crystalline Field on the Magnetic Properties of a Mixed Spin-1/2 and Spin-1 Ising Model
Jozef Strecka, Michal Jascur
The mixed spin-1/2 and spin-1 Ising model in the presence of an anisotropic crystalline field is treated exactly within the framework of an extended star-triangle mapping transform…

Exact results of the one-dimensional tranverse Ising model in an external longitudinal magnetic field
Jozef Strecka, Hana Cencarikova, Michal Jascur
Magnetic properties of the 1D mixed spin-1/2 and spin-S (S >1/2) transverse Ising model in the presence of an external longitudinal magnetic field are calculated exactly by the use…
