标题： Supersymmetric k-defects

摘要： 在超对称理论中，拓扑缺陷的行为可能由缺陷核心中是否恢复超对称性来决定，这种行为可能是非平凡的。 一个著名的例子是，一些超对称宇宙弦会自动具有超导性，从而导致重要的宇宙学效应和约束。 我们研究了在一些粒子物理模型中出现的非平凡动能相互作用对超对称性和弦上超电流之间关系的影响，这些模型在宇宙学中具有重要意义。 我们发现，在某些情况下，额外的相互作用可能会破坏超导性。 显示英文摘要

摘要： In supersymmetric theories, topological defects can have nontrivial behaviors determined purely by whether or not supersymmetry is restored in the defect core. A well-known example of this is that some supersymmetric cosmic strings are automatically superconducting, leading to important cosmological effects and constraints. We investigate the impact of nontrivial kinetic interactions, present in a number of particle physics models of interest in cosmology, on the relationship between supersymmetry and supercurrents on strings. We find that in some cases it is possible for superconductivity to be disrupted by the extra interactions.
