Dynamics of zz spin correlations in the square-lattice spin-1/2 isotropic XY model
Oleg Derzhko, Taras Krokhmalskii
Using the Jordan-Wigner fermionization in two dimensions we obtain the zz wave vector- and frequency-dependent structure factor for the spin-1/2 isotropic XY model on a spatially a…

There is life in the old horse yet or what else we can learn studying spin-1/2 XY chains
Oleg Derzhko
We review some recent results on statistical mechanics of the one-dimensional spin-1/2 XY systems paying special attention to the dynamic and thermodynamic properties of the models…
