Superconformal mechanics of AdS2 D-brane boundstates

Abstract

Abstract We explicitly construct a family of N $$ \mathcal{N} $$ = 4 superconformal mechanics of dyonic particles, generalizing the work of Anninos et al. [1] to an arbitrary number of particles. These mechanics are obtained from a scaling limit of the effective Coulomb branch description of N $$ \mathcal{N} $$ = 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 AdS2 ×S2 ×CY3. 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.
