0 Spin - Peierls instability in the spin - 12 transverse XX chain with Dzyaloshinskii - Moriya interaction
We calculate exactly the density of magnon states of the regularly alternating spin2 XX chain with Dzyaloshinskii-Moriya interaction. The obtained result permit us to examine the stability of the chain with respect to spin-Peierls dimerization. We found that depending on the dependences of Dzyaloshinskii-Moriya interaction on distortion amplitude it may act either in favour of the dimerization ...
متن کاملSpin-Peierls instability in a quantum spin chain with Dzyaloshinskii-Moriya interaction
We analysed the ground state energy of some dimerized spin1 2 transverse XX and Heisenberg chains with Dzyaloshinskii-Moriya (DM) interaction to study the influence of the latter interaction on the spinPeierls 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 DM interaction on the distortion ampli...

in fact this study is concerned with the relationship between the variation in thematice structure and the comprehension of spoken language. so the study focused on the following questions: 1. is there any relationship between thematic structure and the comprehension of spoken language? 2. which of the themes would have greated thematic force and be easier for the subjects to comprehend? accord...
15 صفحه اولthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Magnetic Structure in Spin-peierls Systems
We study theoretically the magnetic structure in the incommensurate phase of spin-Peierls systems under high magnetic fields, utilizing the analytic soliton lattice solution of the mean-field Pytte Hamiltonian. The temperature and field dependence of the magnetic components of the modulated magnetizaton and staggered spin configuration are calculated.
