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.

Considering one-dimensional spin-1/2 isotropic XY model with Dzyaloshinski–Moriya interaction in random Lorentzian transverse field we have calculated exactly thermodynamic quantities of the model. We used the derived average single-particle density of states to examine the validity of coherent potential approximation.

We extend the consideration of the spin- $\frac{1}{2}$ transverse $\mathrm{XY}$ chain with correlated Lorentzian disorder [Phys. Rev. B 55, 14 298 (1997)] for the case of additional Dzyaloshinskii-Moriya interspin interaction. It is shown how the averaged density of states can be calculated exactly. Results are presented for the density of states and the transverse magnetization.We extend the consideration of the spin-$\frac{1}{2}$ transverse $\mathrm{XY}$ chain with correlated Lorentzian disorder [Phys.
