Anomalies in the space of coupling constants and their dynamical applications I
It is customary to couple a quantum system to external classical fields. One application is to
couple the global symmetries of the system (including the Poincar\'{e} symmetry) to …

Anomalies of generalized symmetries from solitonic defects
L Bhardwaj, M Bullimore, AEV Ferrari… - SciPost Physics, 2024 - scipost.org
We propose the general idea that't Hooft anomalies of generalized global symmetries can

The global form of flavor symmetries and 2-group symmetries in 5d SCFTs
group symmetries arise when 1-form symmetries and 0-form symmetries of a theory mix with
each other under group multiplication. We discover the existence of 2-group symmetries in …

Lorentz symmetry fractionalization and dualities in (2+ 1) d
We discuss symmetry fractionalization of the Lorentz group in (2+ 1) d non-spin quantum
field theory (QFT), and its implications for dualities. We prove that two inequivalent non-spin …
