Quantum Field Theory (QFT) is the theoretical framework describing the quantisation of classical fields which allows a Lorentz-invariant formulation of quantum mechanics. QFT is used both in high energy physics as well as condensed matter physics and closely related to statistical field theory. Use this tag for many-body quantum-mechanical problems and the theory of particle physics. Don’t combine with the [quantum-mechanics] tag.

Higher Dijkgraaf-Witten Theory
I am trying to understand higher-form symmetries in TQFT. In particular the higher-form version of Dijkgraaf-Witten Theory.
It is known that for a 0-form symmetry we can specify the principal G-bundle …

Dijkgraaf-Witten for a 2-Group
As a natural extension of my previous question Higher Dijkgraaf-Witten Theory on DW Theory for a 1-form symmetry, we can extend now to 2-groups.
How can we generalize the notion of gauging to a 2-grou …

Hilbert Space in Categorical Gauged TQFT
I am trying to understand how gauge theory interacts with the categorical formulation of TQFT. I will formulate my doubts in two different questions.
I have understood gauging a TQFT in different way …
