We study systems with an Adler-Bell-Jackiw anomaly in terms of non-invertible symmetry. We present a new kind of non-invertible charge defect where a key role is played by a local current operator localized on the defect. The charge defects are now l...

2-group global symmetries are a particular example of how higher-form and conventional global symmetries can fuse together into a larger structure. We construct a theory of hydrodynamics describing the finite-temperature realization of a 2-group glob... Read More about 2-group global symmetries, hydrodynamics and holography.

Higher-form symmetries, anomalous magnetohydrodynamics, and holography (2023)
Journal Article

In U ( 1 ) Abelian gauge theory coupled to fermions, the non-conservation of the axial current due to the chiral anomaly is given by a dynamical operator F μ ν ~ F μ ν constructed from the field-strength tensor. We attempt to describe this physics in... Read More about Higher-form symmetries, anomalous magnetohydrodynamics, and holography.
