Lorentz破坏的Maxwell-Higgs框架中带电BPS涡旋的磁通量反转

Magnetic flux inversion in Charged BPS vortices in a Lorentz-violating Maxwell-Higgs framework

R. Casana, M. M. Ferreira, E. da Hora, C. Miller

摘要:

我们证明了第一个带电的BPS涡的存在,在麦克斯韦-希格斯模型补充奇偶奇洛伦兹违反(LV)结构属于CPT-偶规范扇区的标准模型扩展和四阶电位(在没有陈-西蒙斯项)。修正后的一阶BPS方程提供了一些有趣的特性:局域化和可控的空间厚度,整数磁通量子化,电场反转和局域化的磁通量反转。该模型可以应用于支持携带整数量化磁通量的带电涡旋的凝聚态系统,赋予局部翻转的磁通量。

英文摘要:

We demonstrate for the first the existence of electrically charged BPS vortices in a Maxwell-Higgs model supplemented with a parity-odd Lorentz-violating (LV) structure belonging to the CPT-even gauge sector of the standard model extension and a fourth order potential (in the absence of the Chern-Simons term). The modified first order BPS equations provide charged vortex configurations endowed with some interesting features: localized and controllable spatial thickness, integer flux quantization, electric field inversion and localized magnetic flux reversion. This model could possibly be applied on condensed matter systems which support charged vortices carrying integer quantized magnetic flux, endowed with localized flipping of the magnetic flux.
