研究了玻色子超导弦的四次有效势和Coleman-Weinberg有效势的经典解。我们映射了解的参数空间，讨论并量化了带电凝聚物对涡旋的反作用。我们解决了临界电流和淬火转变的问题。我们考虑静态环路配置，其中电磁应力平衡环路串的张力。这样的静态循环只存在于参数空间的一个非常小的区域。我们还给出了任意希格斯玻色子与矢量质量之比下非超导测量弦每长度能量的精确结果。
We study the classical solutions of bosonic superconducting strings for quartic and Coleman-Weinberg effective potentials. We map the parameter space of solutions, and discuss and quantify back reaction of the charged condensate upon the vortex. We address the issue of the critical current and the quench transition. We consider static loop configurations in which electromagnetic stresses balance the loop string tension. Such static loops are shown to exist only in a very small region of the parameter space. We also give accurate results for the energy per length of a nonsuperconducting gauged string for arbitrary ratio of Higgs-boson to vector mass.
