Title: Probing boundary states at finite coupling
Abstract: In this talk, we calculate exactly the correlation function of a Wilson loop operator and a local non-BPS operator in planar N=4 SYM. First, we introduce an effective theory for such observable in free theory and we reformulate the gauge-theory computation as an overlap between an energy eigenstate of a spin-chain and a matrix product state. The form of the result supports the interpretation of the correlator as an overlap between an integrable boundary state, which we determine using symmetry and integrability, and the state corresponding to the single-trace operator. Second, we explain how to formulate a non-perturbative bootstrap program based on the results obtained in this framework.
We also discuss two applications of the effective theory to the four-point function of determinant operators in N=4 SYM, as well as to all-loop determinant correlators in the fishnet theory.
