Thermodynamics of the s=1/2 transverse XX chain with Dzyaloshinskii-Moriya interaction in the presence of correlated Lorentzian disorder
O. Derzhko, J. Richter, V. Derzhko
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 c…

Spin-1/2 periodic nonuniform XX chains and the spin-Peierls instability
O. Derzhko, J. Richter, O. Zaburannyi
Using continued fractions we obtained the exact result for the density of magnon states of the regularly alternating spin-1/2 XX chain with Dzyaloshinskii-Moriya interaction. We ex…
