Abstract

Using continued fractions we obtained the exact result for the density of magnon states of the regularly alternating spin-1/2 XX chain with the Dzyaloshinskii-Moriya interaction.We examined the stability of the magnetic chain with respect to the spin-Peierls dimerization.

Spin-Peierls instability in a quantum spin chain with Dzyaloshinskii-Moriya interaction

Oleg Derzhko, Johannes Richter, O. Zaburannyi

We analysed the ground-state energy of some dimerized spin-1/2 transverse XX and Heisenberg chains with Dzyaloshinskii-Moriya (DM) interaction to study the influence of the latter interaction on the spin-Peierls instability. We found that DM interaction may act either in favour of the dimerization or against it. The actual result depends on the dependence of the DM interaction on the distortion amplitude in comparison with such dependence for the isotropic exchange interaction.

The ground state properties of the spin-½ transverse Ising chain with periodically varying bonds and fields

Oleg Derzhko

Using continued fractions we study the ground state properties of the spin-½ Ising chain in a transverse field with periodically varying interaction strengths and external fields. We consider in detail the chain having a period-2 modulation of the interaction strengths and compare the results obtained with those corresponding to the spin-½ isotropic XY chain in a transverse field. In contrast to the behaviour of the transverse XY chain, the transverse Ising chain does not exhibit a step-like magnetization versus field dependence caused by the alternation of bonds. Its susceptibility exhibits a logarithmic singularity at a field determined by interaction strengths, and it is stable with respect to spin-Peierls dimerization.

The influence of dzyaloshinskii-moriya interaction on the dimerization in Spin-Peierls systems

Zhiguo Wang

By Lanczos numerical method. The influence of Dzyaloshinskii-Moriya(D-M) interaction on the dimer-ization in Spin-Peierls systems is studied. The ground sate of the Spin-Peierls system is still a dimerized phase when D-M interaction is present. The results show that the uniform D-M interaction is always against dimeriza-tion but the staggered D-M interaction may act in favour of or against dimerization. There exists a critical point where the staggered D-M interaction has no influence on dimerization.
