摘要:

我们证明了在具有Dzyaloshinskiii-Moryia交换和强易面各向异性的手征helimagnet中,在拓扑基态组态上存在孤立孤子激发。垂直于螺旋轴的磁场稳定了扭折晶体态,对具有一定旋向性的孤子起着“拓扑保护”的作用。为了得到新的孤子解,我们采用了贝克隆变换技术。指出孤子携带着磁振子密度,可以实现磁孤子输运。

英文摘要:

We show the existence of an isolated soliton excitation over the topological ground state configuration in chiral helimagnet with the Dzyaloshinskii-Moryia exchange and the strong easy-plane anisotropy. The magnetic field perpendicular to the helical axis stabilizes the kink crystal state which plays a role of "topological protectorate" for the traveling soliton with a definite handedness. To find new soliton solution, we use the Bäcklund transformation technique. It is pointed out that the traveling soliton carries the magnon density and a magnetic solition transport may be realized.
