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…
