Q-operators are 't Hooft lines (2103.01835v1)
Published 2 Mar 2021 in hep-th, cond-mat.stat-mech, and math.QA
Abstract: We study 't Hooft lines in four-dimensional holomorphic-topological Chern-Simons theory. We relate them to Q-operators in the theory of integrable systems. We give a physical interpretation of the fundamental TQ and QQ relations satisfied by Q-operators and conventional transfer matrices.
