't Hooft loop

The 't Hooft loop is a concept from theoretical physics, particularly in the context of gauge theories, including quantum field theories and string theories. It is named after the physicist Gerard 't Hooft, who made significant contributions to our understanding of gauge theories. In a gauge theory, the 't Hooft loop is an operator that creates a magnetic monopole-like configuration or represents the dual description of certain non-abelian gauge theories.
