Topological Quantum Field Theory, Nonlocal Operators, and Gapped Phases of Gauge Theories

Gukov, Sergei, Kapustin, Anton

Understand

We revisit the role of loop and surface operators as order parameters for gapped phases of four-dimensional gauge theories.

  • We show that in some cases surface operators are confined, and that this fact can be used to distinguish phases which are not distinguished by the Wilson-'t Hooft criterion.
  • The long-distance behavior of loop and surface operators which are neither confined nor screened is controlled by a 4d TQFT.
  • We construct these TQFTs for phases which are characterized by the presence of electrically and/or magnetically charged condensates.
