小型空心磁单极子

Small and hollow magnetic monopoles

D. Bazeia, M. A. Marques, Gonzalo J. Olmo

摘要:

我们处理的存在下的磁单极子在一个非阿贝尔模型,推广了标准的t~Hooft-Polyakov模型在三维空间。我们研究静态和球对称解的能量密度,以找到解决运动方程的一阶微分方程。进一步研究了该系统,得到了两类不同的解,一类解也可以用解析解来描述,称为小解,因为它明显小于标准的t~Hooft-Polyakov解。另一种类型的结构是中空的,因为能量密度在其核心处被赋予了孔。中空的导磁层可以比标准导磁层更小或更大,这取决于控制模型的磁导率的参数值。

英文摘要:

We deal with the presence of magnetic monopoles in a non Abelian model that generalizes the standard 't~Hooft-Polyakov model in three spatial dimensions. We investigate the energy density of the static and spherically symmetric solutions to find first order differential equations that solve the equations of motion. The system is further studied and two distinct classes of solutions are obtained, one that can also be described by analytical solutions which is called small monopole, since it is significantly smaller than the standard 't~Hooft-Polyakov monopole. The other type of structure is the hollow monopole, since the energy density is endowed with a hole at its core. The hollow monopole can be smaller or larger than the standard monopole, depending on the value of the parameter that controls the magnetic permeability of the model.
