| contents | We introduce a large class of $θ$ angles in quantum field theory that we call symmetry $θ$ angles. Unlike conventional $θ$ angles whose definition depends on a choice of a path integral, symmetry $θ$ angles are intrinsic parameters of a quantum field theory that depend only on its symmetries. A frequent consequence of symmetry $θ$ angles is a phenomenon we call the topological Witten effect, which is a generalization of the standard Witten effect. Topological Witten effects modify which charged operators are attached to topological operators as a function of $θ$. Physically, topological Witten effects induce generalized Aharonov-Bohm effects. We show that these new $θ$ angles and Witten effects can appear in many familiar field theories. |
