Abstract
The thermodynamics of the one-dimensional spin 1/2 isotropic XY model with Dzyaloshinskii-Moriya interaction in random Lorentzian transverse field has been obtained exactly. Using the derived exact single-particle density of states, the validity of coherent potential approximation has been examined.
