Jordan-Wigner approach to the frustrated spin one-half XXZ chain
T. Verkholyak, A. Honecker, W. Brenig
The Jordan-Wigner transformation is applied to study the ground state properties and dimerization transition in the chain. We consider different solutions of the me…

Jordan-Wigner fermions and the spin-1/2 anisotropic XY model on a square lattice
Oleg Derzhko, Johannes Richter, Taras Verkholyak
Using the two-dimensional Jordan-Wigner fermionization we calculate the thermodynamic quantities of the (spatially anisotropic) square-lattice spin-1/2 anisotropic XY (XZ) model. W…

Investigation of ferroelectric order-disorder type compounds with asymmetric double-well potential
R. R. Levitskii, T. M. Verkholyak, I. V. Kutny +1
The Mitsui model for the order-disorder type ferroelectrics is studied within the mean field approximation. The phase diagram of the model is obtained, its dependence on the transv…
