Thermodynamics of the s=1/2 transverse XX chain with Dzyaloshinskii-Moriya interaction in the presence of correlated Lorentzian disorder

TL;DR

This paper investigates how correlated Lorentzian disorder affects the thermodynamics of the spin-1/2 transverse XX chain with Dzyaloshinskii-Moriya interaction, revealing nonzero average magnetization due to asymmetries in the density of states.

Contribution

It introduces analysis of the thermodynamic behavior of the XX chain with correlated disorder and Dzyaloshinskii-Moriya interaction, highlighting the impact on magnetization and density of states asymmetry.

Findings

Correlated disorder induces nonzero average transverse magnetization.

Asymmetry in the density of states explains the magnetization behavior.

Disorder affects the moments of the density of states.

Abstract

The spin-1/2 transverse XY chain with correlated disorder may exhibit the nonzero averaged transverse magnetization at zero averaged transverse field. We discuss this peculiarity connected with asymmetry in the density of states and induced by the correlated disorder analysing the moments of the density of states.
