On ’t Hooft defects, monopole bubbling and supersymmetric quantum mechanics
Abstract
We revisit the localization computation of the expectation values of ’t Hooft operators in N = 2* SU(N) theory on R ^{3} × S ^{1}. We show that the part of the answer arising from “monopole bubbling” on R ^{3} can be understood as an equivariant integral over a KronheimerNakajima moduli space of instantons on an orbifold of C ^{2}. It can also be described as a Witten index of a certain supersymmetric quiver quantum mechanics with N = (4, 4) supersymmetry. The map between the defect data and the quiver quantum mechanics is worked out for all values of N. For the SU(2) theory, we compute several examples of these line defect expectation values using the Witten index formula and confirm that the expressions agree with the formula derived by Okuda, Ito and Taki. In addition, we present a Type IIB construction — involving D1D3NS5branes — for monopole bubbling in N = 2* SU(N) SYM and demonstrate how the quiver quantum mechanics arises in this brane picture.
