各向同性反铁磁体中的孤子：超越西格玛模型
Solitons in isotropic antiferromagnets: beyond a sigma model
摘要：
各向同性反铁磁体中存在大量的磁孤子，它们具有非平凡的静态和动态特性。一维孤子元激发具有周期性色散规律。对于二维情形，存在具有非奇异宏观核的平面反铁磁涡旋，其核具有饱和的磁矩。这些平面反铁磁涡旋的动力学性质的特点是存在一个回转力
英文摘要：
Isotropic antiferromagnets shows a reach variety of magnetic solitons with non-trivial static and dynamic properties. One-dimensional soliton elementary excitations have a periodic dispersion law. For two-dimensional case, planar antiferromagnetic vortices having non-singular macroscopic core with the saturated magnetic moment are present. The dynamic properties of these planar antiferromagnetic vortex are characterized by presence of a gyroforce
