We consider the s = 1/2 transverse XX chain with the Dzyaloshinskii-Moriya (DM) interaction directed along z-axis in spin space to examine the effects of the DM interaction on the zz, xx (yy) and xy (yx) dynamic structure factors. With the help of a unitary transformation, the DM interaction can be eliminated resulting in a renormalized isotropic (XX) exchange interaction. The zz dynamic structure...
