具有N个标量场的超对称阿贝尔Higgs模型存在多个畴壁解。我们执行一个Callias型指数计算,以确定该孤子的零模式的数量。我们确认,最一般的畴壁有$2(N\ensuremath{-}1)$零模式,这可以解释为位置和相位的$(N\ensuremath{-}1)$组成畴壁。这意味着在IIB型弦理论中,在N个D5 $-膜之间的D-弦内插模的存在。
The supersymmetric Abelian Higgs model with N scalar fields admits multiple domain wall solutions. We perform a Callias-type index calculation to determine the number of zero modes of this soliton. We confirm that the most general domain wall has $2(N\ensuremath{-}1)$ zero modes, which can be interpreted as the positions and phases of $(N\ensuremath{-}1)$ constituent domain walls. This implies the existence of moduli for a D-string interpolating between N $D5$-branes in type IIB string theory.
