Supersymmetric Mixed Boundary Conditions in AdS2 and DCFT1 Marginal Deformations
Abstract
We consider different supersymmetric mixed boundary conditions for scalar and fermionic fields in AdS2, searching for the dual description of a family of interpolating Wilson Loops in ABJM theory. The family, which interpolates between the bosonic 1/6 BPS loop and the 1/2 BPS loop, can be thought of as an exact marginal deformation in a defect CFT1. Confronting this property against holographic correlators and vacuum energy corrections singles out a particular boundary condition which we propose as dual to the interpolating family of Wilson loops.
