论文摘要
我们明确地构建了一个$ {\ cal n} = 4 $的二射颗粒的超符合力学的家族，从而推广了Anninos等人的工作，\ \，\ cite {Anninos：2013nra}到任意数量的粒子。这些力学是从$ {\ Mathcal n} = 4 $ Quiver量子量子力学的有效库仑分支描述的缩放限制中获得的，这些机制描述了II型Calabi-yau压缩中的D-Branes。在这些d-branes的超级描述中，此限制将渐近剂更改为广告$ _2 \ times $ s $^2 \ times $ cy $ _3 $。我们展示了$ d（1,2; 0）$详细的机械师的超符号对称性和保守的费用。此外，我们在Hyperkähler歧管上提出了一种替代公式，作为Sigma模型。
We explicitly construct a family of ${\cal N}=4$ superconformal mechanics of dyonic particles, generalizing the work of Anninos et al.\,\cite{Anninos:2013nra} to an arbitrary number of particles. These mechanics are obtained from a scaling limit of the effective Coulomb branch description of ${\mathcal N}=4$ quiver quantum mechanics describing D-branes in type II Calabi-Yau compactifications. In the supergravity description of these D-branes this limit changes the asymptotics to AdS$_2\times $S$^2\times$CY$_3$. We exhibit the $D(1,2;0)$ superconformal symmetry and conserved charges of the mechanics in detail. In addition we present an alternative formulation as a sigma model on a hyperkähler manifold with torsion.
