Francisco Navarro-Lerida, Eugen Radu, D. H. Tchrakian

摘要:

研究了$4+1$维阿贝尔规范$O(5)$ Skyrme模型,其中包含$F^4$ Maxwell项和Chern-Simons项.我们的目的是揭示机制,发现在类似的阿贝尔规范$O(3)$ Skyrme模型在$2+1$维,这导致了不寻常的关系的质量-能量$E$的电荷$Q_e$和角动量$J$,并在“重子数”$q$的值的变化,由于阿贝尔场对Skyrmion的影响。Chern-Simons动力学与规范Skyrme标量的动力学一起,允许具有不同磁场渐近值的解决方案,导致列出这些不寻常的属性。数值计算工作是在一个有效的一维子系统上进行的,该子系统是在${\mathbb R}^4$上施加增强的径向对称性而产生的。

英文摘要:

We study an Abelian gauged $O(5)$ Skyrme model in $4+1$ dimensions, featuring the $F^4$ Maxwell and the Chern-Simons terms. Our aim is to expose the mechanism, discovered in the analogous Abelian gauged $O(3)$ Skyrme model in $2+1$ dimensions, which leads to the unusual relation of the mass-energy $E$ to the electric charge $Q_e$ and angular momentum $J$, and, to the change in the value of the "baryon number" $q$ due to the influence of the Abelian field on the Skyrmion. Chern-Simons dynamics together with the dynamics of the gauged Skyrme scalar, allows for solutions with varying asymptotic values of the magnetic field, resulting in these unusual properties listed. Numerical work is carried out on an effective one dimensional subsystem resulting from imposition of an enhaced radial symmetry on ${\mathbb R}^4$.
