Polyakov's confinement mechanism for generalized Maxwell theory
Matthew Heydeman, Christian B. Jepsen, Ziming Ji +1
We study fractional-derivative Maxwell theory, as appears in effective descriptions of, for example, large QED, graphene, and some types of surface defects. We argue th…
A tale of two moduli spaces: logarithmic and multi-scale differentials
Dawei Chen, Samuel Grushevsky, David Holmes +2
Multi-scale differentials were constructed by M.~Bainbridge, D.~Chen, Q.~Gendron, S.~Grushevsky, and M.~Möller, from the viewpoint of flat and complex geometry, for the purpose of…
Non-Invertible Gauss Law and Axions
Yichul Choi, Ho Tat Lam, Shu-Heng Shao
In axion-Maxwell theory at the minimal axion-photon coupling, we find non-invertible 0- and 1-form global symmetries arising from the naive shift and center symmetries. Since the G…
Argyres-Douglas Avatars of Coulomb Branch Physics
Chinmaya Bhargava, Matthew Buican, Hongliang Jiang
We study ultraviolet (UV) incarnations of deep infrared (IR) physics on the Coulomb branch of the simplest interacting 4D superconformal field theory: the minimal A…
Exotic Dehn twists on sums of two contact 3-manifolds
Eduardo Fernández, Juan Muñoz-Echániz
We exhibit the first examples of exotic contactomorphisms with infinite order as elements of the contact mapping class group. These are given by certain Dehn twists on the separati…
Remarks on Berry Connection in QFT, Anomalies, and Applications
Mykola Dedushenko
Berry connection has been recently generalized to higher-dimensional QFT, where it can be thought of as a topological term in the effective action for background couplings. Via the…
