Incommensurate Spin-Peierls Phases in the One-Dimensional Quantum Isotropic XY Model
Oleg Derzhko, Taras Krokhmalskii
Using the numerical approach for a study of the thermodynamic properties of the nonuniform one-dimensional spin-1/2 isotropic XY model in a transverse field we examine different la…

Spin-1/2 transverse XX chain with a correlated disorder: dynamics of the transverse correlations
Oleg Derzhko, Taras Krokhmalskii
We examine numerically the dynamics of zz correlations in the spin-1/2 isotropic XY chain with random intersite coupling and on-site transverse field that depends linearly on the n…
