标题： Gauge string in the fermion asymmetric matter

摘要： 在具有矢量场与费米子异常耦合的规范模型中，考虑了规范弦与均匀费米子密度相互作用的两个新效应。 首先，证明了直弦上存在感应的非零磁类似螺旋度。 其次，表明弦的运动方程被一个非线性项修改，该非线性项可以分解为对弦张力的修正和一个垂直于弦切向和法向矢量的附加力。 找到了静态构型并研究了它们的稳定性。 显示英文摘要

摘要： Two new effects of interaction of the gauge string with a homogeneous density of fermions are considered in a gauge model with an anomalous coupling of vector fields with fermions. First, the presence of an induced nonzero magnetic-like helicity on the straight string is demonstrated. Second, it is shown that the equation of motion of the string is modified by a nonlinear term that can be decomposed into the correction to the string tension and an additional force perpendicular to the tangent and normal vectors of the string. Static configurations are found and their stability is studied.
