We present an analytic study of domain-wall statics and dynamics in ferromagnetic nanotubes with spin-orbit-induced Dzyaloshinskii-Moriya interaction (DMI). Even at the level of statics, dramatic effects arise from the interplay of space curvature and DMI: the domains become chirally twisted, leading to more compact domain walls. The dynamics of these chiral structures exhibits several interesting features. Under weak applied currents, they propagate without distortion. The dynamical response is further enriched by the application of an external magnetic field: the domain-wall velocity becomes chirality dependent and can be significantly increased by varying the DMI. These characteristics allow for enhanced control of domain-wall motion in nanotubes with DMI, increasing their potential as information carriers in future logic and storage devices.
