Ground-state phase diagram of geometrically frustrated Ising-Heisenberg model on doubly decorated planar lattices
Lucia Canova, Jozef Strecka, Jan Dely +1
Ground-state phase diagram of the mixed spin-1/2 and spin-1 Ising-Heisenberg model on doubly decorated planar lattices is examined using the generalized decoration-iteration transf…

Reentrant transitions of Ising-Heisenberg ferromagnet on a triangular lattice with diamond-like decorations
Michal Jascur, Jozef Strecka, Lucia Canova
The mixed spin-1/2 and spin-1 Ising-Heisenberg ferromagnet on the decorated triangular lattice consisting of inter-connected diamonds is investigated within the framework of an exa…

The spin-1/2 Ising model on the bow-tie lattice as an exactly soluble free-fermion model
Jozef Strecka, Lucia Canova
The spin-1/2 Ising model on the bow-tie lattice is exactly solved by establishing a precise mapping relationship with its corresponding free-fermion eight-vertex model. Ground-stat…
