There is life in the old horse yet or what else we can learn studying spin-1/2 XY chains

Abstract

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 with Dzyaloshinskii-Moriya interaction, correlated disorder, and regularly alternating Hamiltonian parameters.Comment: 21 pages, 4 figure
