Quantum spin chains with regularly alternating bonds and fields
Oleg Derzhko
We consider the spin-1/2 XY chain in a transverse field with regularly varying exchange interactions and on-site fields. In two limiting cases of the isotropic XX and extremely ani…

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…

Jordan-Wigner fermionization for spin-1/2 systems in two dimensions: A brief review
Oleg Derzhko
We review the papers on the Jordan-Wigner transformation in two dimensions to comment on a possibility of examining the statistical mechanics properties of two-dimensional spin-1/2…
