Description
Conformal symmetry introduces two predominant complications into one dimensional sigma models by constraining the target space geometry to a cone. Namely, the naive spectrum of the corresponding quantum mechanics suffers from the noncompactness and singularity issues, thus rendering the Witten index an ill-defined object. We demonstrate how these challenges can be overcome by introducing a refined superconformal index, computed through localization for a general class of N=(0,2) models. These models are expected to play a significant role in a top-down understanding of AdS(2)/CFT(1) duality. More concretely, we will discuss an application for the Coulomb branch of the quiver mechanics which describes the bound states of D-branes.
