Random s=1/2 XY chains and the theory of quasi-one-dimensional ferroelectrics with hydrogen bonds
O. Derzhko, T. Krokhmalskii
Abstract
The paper presents a new numerical approach for studying the thermodynamical and dynamical properties of finite spin-12 XY chains. Special attention is given to examining the influence of disorder on the average transverse dynamical susceptibility of Ising chain in random transverse field.
