局部D维整体k-亏损
Localized D-dimensional global k-defects
摘要：
通过考虑D+1维Minkowski时空中具有非标准动力学项的作用所描述的最大对称解，我们明确地证明了任意维数的静态全局亏损解的存在性，其能量在空间无穷远不发散.我们分析确定的缺陷分布在小和大的距离，从缺陷中心。我们验证了这种解决方案的稳定性，并讨论了我们的研究结果可能产生的影响，特别是暗物质和石墨烯中的电荷分馏。
英文摘要：
We explicitly demonstrate the existence of static global defect solutions of arbitrary dimensionality whose energy does not diverge at spatial infinity, by considering maximally symmetric solutions described by an action with non-standard kinetic terms in a D+1 dimensional Minkowski space-time. We analytically determine the defect profile both at small and large distances from the defect centre. We verify the stability of such solutions and discuss possible implications of our findings, in particular for dark matter and charge fractionalization in graphene.
