论文摘要
考虑到均匀介质中非层次级涡流字符串的形状和动力学，在将问题减少到找到Abelian Higgs模型的极端情况下，使用固定的B型螺旋性的量表模型。结果表明，与固定的A型螺旋性相反，Ginzburg-Landau能量功能在伦敦极限中的静态解决方案是螺旋螺旋，其曲率与涡流线之间的特定关系取决于违反Lifshitz Invariant的空间均值的强度。在螺旋轮廓周围的小振荡的情况下，将非线性动力学方程式定为线性化，并且获得了传播波的极化和分散定律。
The shape and dynamics of the nonrelativistic gauge vortex string in the parity-broken media is considered, upon reducing the problem to finding the extremum of the Abelian Higgs model effective action with the fixed B-type helicity of the gauge field. It is shown that in contrast with the case of the fixed A-type helicity, the static solution of the Ginzburg-Landau energy functional in the London limit is the helix with the specific relation between the curvature and torsion of the vortex line depending on the strength of the space parity violating contribution of the Lifshitz invariant. A nonlinear dynamical equation is linearized in case of small oscillations around the helical contour, and the polarization and dispersion law of the propagated waves are obtained.
