Dynamic Structure Factors of the Spin-1/2XXChain with Dzyaloshinskii–Moriya Interaction

Abstract

We consider the spin-1/2 isotropic XY chain in a (z) transverse magnetic field with the Dzyaloshinskii-Moriya interaction directed along the z-axis in spin space and examine the effects of the latter interaction on the zz, xx (yy) and xy (yx) dynamic structure factors. The Dzyaloshinskii-Moriya interaction does not manifest itself in the zz dynamic quantities. In contrast, the xx (yy) and xy (yx) dynamic structure factors show dramatical changes owing to the Dzyaloshinskii-Moriya interaction. Implications of our results for electron spin resonance experiments are briefly discussed.

Dynamic probes of quantum spin chains with the Dzyaloshinskii-Moriya interaction

We consider the spin-$\frac{1}{2}$ anisotropic $XY$ chain in a transverse $(z)$ field with the Dzyaloshinskii-Moriya interaction directed along the $z$ axis in spin space to examine the effect of the Dzyaloshinskii-Moriya interaction on the $zz$, $xx$, and $yy$ dynamic structure factors. Using the Jordan-Wigner fermionization approach we analytically calculate the dynamic transverse spin structure factor. It is governed by a two-fermion excitation continuum. We analyze the effect of the Dzyaloshinskii-Moriya interaction on the two-fermion excitation continuum. Other dynamic structure factors which are governed by many-fermion excitations are calculated numerically. We discuss how the Dzyaloshinskii-Moriya interaction manifests itself in the dynamic properties of the quantum spin chain at various fields and temperatures.

Dynamics of the spin-½ isotropicXYchain in a transverse field

Oleg Derzhko, Taras Krokhmalskii, Joachim Stolze

Dynamic xx and xy spin pair correlation functions for the isotropic spin-½ XY chain are calculated numerically for long open chains in the presence of a transverse ( z ) magnetic field at finite temperature. From these data the first numerical results for the dynamic structure factors S xx (κ,ω) and S xy (κ,ω) are obtained and compared with the known results for S zz (κ,ω). While S zz (κ,ω) is restricted to certain regions in the (κ,ω)-plane S xx (κ,ω) and S xy (κ,ω) are not. Nevertheless, the numerical results show that the latter structure factors are quite small outside the regions defined by S zz (κ,ω) and moreover, that they may in many circumstances, especially at low temperature, be approximately described by a small number of broadened excitation branches.

Dynamic properties of the dimerized spin-½ isotropicXYchain in a transverse field

Oleg Derzhko, Taras Krokhmalskii, Joachim Stolze

The zz and xx ( yy ) dynamic structure factors of the dimerized spin-½ isotropic XY chain in a transverse ( z ) field are calculated for arbitrary temperatures. The zz structure factor can be given in analytical terms, involving a single integration, whereas the xx dynamic structure factor can be evaluated completely numerically for very long chains. We compare the two structure factors and discuss in some detail how a dimerization manifests itself in the dynamic structure factors at different external fields and temperatures. We compare our results to corresponding results for the dimerized Heisenberg chain obtained by approximate techniques.

We examine dynamic quantities of a random spin-1/2 isotropic XY chain in a transverse field.The randomness is related to the sign of the nearest-neighbor exchange interaction and can be eliminated by a suitable transformation.As a result, the dynamic quantities for the random spin chain are related to the same dynamic quantities for the homogeneous spin chain.We use the available results for the latter model to discuss the effect of randomness on the dynamic structure factors of the quantum spin chain.

Spin-1/2 isotropic XY chain with Dzyaloshinskii-Moriya interaction in random lorentzian transverse field

Oleg Derzhko, Taras Verkholyak

The exact results for thermodynamical properties of one-dimensional spin-1/2 isotropic XY model with Dzyaloshinskii-Moriya interaction in random lorentzian transverse field are obtained. This permits to discuss some approximate methods of disordered spin systems theory. The approximate scheme of examining the thermodynamics of one-dimensional spin-1/2 XXZ Heisenberg model with Dzyaloshinskii-Moriya interaction in random lorentzian field is suggested.
