Title: Wilson Loop, Matrix Product State, and Integrability

Abstract: I will discuss a reformulation of Wilson loops in large N gauge theories as matrix product states. The construction is motivated by the analysis of supersymmetric Wilson loops in N=4 super-Yang Mills (SYM) but it can be applied more generally to large N gauge theories and matrix models, although less effective. For N=4 SYM, one can even perform the computation exactly as a function of the coupling constant by combining this idea with the underlying integrable structure of the theory. This also reveals an interesting connection between the bond dimension of matrix product states and degrees of freedom localized at the boundary of the dual string worldsheet.
