Generalized symmetries of topological field theories
Journal of High Energy Physics, 2023 We study generalized symmetries in a simplified arena in which the usual quantum field theories of physics are replaced with topological field theories and the smooth structure with which the symmetry groups of physics are usually endowed is forgotten ...

Perturbing topological field theories [PDF]
Physical Review D, 1999 The abelian Chern-Simons theory is perturbed by introducing local gauge-invariant interaction terms depending on the curvature. The computation of the correlation function of two Wilson lines for two smooth closed nonintersecting curves is reported up to four loops and is shown to be unaffected by radiative corrections.

Balanced Topological Field Theories [PDF]
Communications in Mathematical Physics, 1997 We describe a class of topological field theories called ``balanced topological field theories.'' These theories are associated to moduli problems with vanishing virtual dimension and calculate the Euler character of various moduli spaces. We show that these theories are closely related to the geometry and equivariant cohomology of ``iterated ...

Topological field theories and symmetry protected topological phases with fusion category symmetries
Journal of High Energy Physics, 2021 Fusion category symmetries are finite symmetries in 1+1 dimensions described by unitary fusion categories. We classify 1+1d time-reversal invariant bosonic symmetry protected topological (SPT) phases with fusion category symmetry by using topological ...

Intrinsic sign problems in topological quantum field theories
Physical Review Research, 2020 The sign problem is a widespread numerical hurdle preventing us from simulating the equilibrium behavior of various problems at the forefront of physics.

Non-local order parameters and quantum entanglement for fermionic topological field theories
Journal of High Energy Physics, 2020 We study quantized non-local order parameters, constructed by using partial time-reversal and partial reflection, for fermionic topological phases of matter in one spatial dimension protected by an orientation reversing symmetry, using topological ...

Topological defects in nonlocal field theories
Journal of High Energy Physics, 2022 In this paper we study for the first time topological defects in the context of nonlocal field theories in which Lagrangians contain infinite-order differential operators. In particular, we analyze domain walls.

Constrained topological field theory [PDF]
Physics Letters B, 1994 We derive a model of constrained topological gravity, a theory recently introduced by us through the twist of N=2 Liouville theory, starting from the general BRST algebra and imposing the moduli space constraint as a gauge fixing. To do this, it is necessary to introduce a formalism that allows a careful treatment of the global and the local degrees of

A Cellular Topological Field Theory [PDF]
Communications in Mathematical Physics, 2020 We present a construction of cellular BF theory (in both abelian and non-abelian variants) on cobordisms equipped with cellular decompositions. Partition functions of this theory are invariant under subdivisions, satisfy a version of the quantum master equation, and satisfy AtiyahâSegal-type gluing formula with respect to composition of cobordisms.
