非阿贝尔涡旋、超杨-米尔斯理论和自旋(7)瞬子

Non-Abelian Vortices, Super-Yang-Mills Theory and Spin(7)-Instantons

Alexander D. Popov

摘要:

我们考虑八维流形R^2 x G/H上的复向量丛E,其中G/H = SU(3)/U(1)xU(1)是一个齐次空间,具有一个永不可积的几乎复结构和一族SU(3)-结构.我们建立了R^2 × G/H上自旋(7)瞬子方程的G不变解A与R^2上非阿贝尔耦合涡旋方程的一般解之间的等价性。这些涡旋是在具有SU(3)-结构的陪集空间G/H上紧化的N=1超对称杨-米尔斯十维规范理论(d=4规范理论)中的BPS孤子。所得涡旋方程的新颖之处在于,定义R^2上矢量丛态射的希格斯场在一般情况下不是全纯的。最后,我们引入了N=4超Yang-Mills理论中的BPS涡方程,并证明了它们具有相同的性质。

英文摘要:

We consider a complex vector bundle E endowed with a connection A over the eight-dimensional manifold R^2 x G/H, where G/H = SU(3)/U(1)xU(1) is a homogeneous space provided with a never integrable almost complex structure and a family of SU(3)-structures. We establish an equivalence between G-invariant solutions A of the Spin(7)-instanton equations on R^2 x G/H and general solutions of non-Abelian coupled vortex equations on R^2. These vortices are BPS solitons in a d=4 gauge theory obtained from N=1 supersymmetric Yang-Mills theory in ten dimensions compactified on the coset space G/H with an SU(3)-structure. The novelty of the obtained vortex equations lies in the fact that Higgs fields, defining morphisms of vector bundles over R^2, are not holomorphic in the generic case. Finally, we introduce BPS vortex equations in N=4 super Yang-Mills theory and show that they have the same feature.
