Symmetry Transmutation and Anomaly Matching
Nathan Seiberg, Sahand Seifnashri
We explore a situation where a global symmetry of the ultraviolet (UV) theory does not act faithfully on the local infrared (IR) degrees of freedom, but instead acts effectively as…
Gauging non-invertible symmetries on the lattice
Sahand Seifnashri, Shu-Heng Shao, Xinping Yang
We provide a general prescription for gauging finite non-invertible symmetries in 1+1d lattice Hamiltonian systems. Our primary example is the Rep(D) fusion category generated…
Line Operators of Gauge Theories on Non-Spin Manifolds
J. P. Ang, Konstantinos Roumpedakis, Sahand Seifnashri
We study four-dimensional gauge theories on oriented and non-spin spacetime manifolds. On such manifolds, each line operator arises only either as a boson or a fermion. Based on ph…
3D Dualities and Supersymmetry Enhancement from Domain Walls
Martin Roček, Konstantinos Roumpedakis, Sahand Seifnashri
We test recently proposed IR dualities and supersymmetry enhancement by studying the supersymmetry on domain walls. In the Wess-Zumino model studied in arXiv:1804.02018 and…
