New AdS2 backgrounds and N=4 conformal quantum mechanics

We present a new infinite family of Type IIB backgrounds with an AdS(2) factor, preserving N = 4 SUSY. For each member of the family we propose a precise dual Super Conformal Quantum Mechanics (SCQM). We provide holographic expressions for the number of vacua (the central charge), Chern-Simons terms and other non-perturbative aspects of the SCQM. We relate the central charge of the one-dimensional system with a combination of electric and magnetic fluxes in Type IIB. The Ramond-Ramond fluxes are used to propose an extremisation principle for the central charge. Other physical and geometrical aspects of these conformal quantum mechanics are analysed.

Automated summary

A new infinite family of Type IIB backgrounds with an AdS(2) factor is presented, each with a proposed dual Super Conformal Quantum Mechanics (SCQM) model. Holographic expressions for the number of vacua, Chern-Simons terms, and other non-perturbative aspects of the SCQM are provided. The central charge of the one-dimensional system is related to a combination of electric and magnetic fluxes in Type IIB, with an extremisation principle proposed using Ramond-Ramond fluxes. Other physical and geometrical aspects of these conformal quantum mechanics are analyzed.
