Dynamics of transverse correlations in the spin-1/2 isotropic XY chain with a correlated Lorentzian disorder
Oleg Derzhko, Taras Krokhmalskii
Abstract
Using a numerical approach we examine the dynamics of zz correlations for the spin-12 isotropic XY chain with random Lorentzian intersite coupling and transverse field at sites that depends linearly on the neighbouring couplings. We study in detail the wave vector- and frequency-dependent zz structure factor at different values of Hamiltonian parameters and temperature. We discuss the changes in the frequency profiles of the zz dynamic structure factor caused by the introduced correlated disorder.
