Non-Invertible Symmetries and Boundaries for Two-Dimensional Fermions
Guillermo Arias-Tamargo, Philip Boyle Smith, Rishi Mouland +1
We study the relation between boundary conditions and categorical symmetries of two-dimensional fermionic conformal field theories. We determine all anomaly-free invertible global…
On Generalised Discrete Torsion
Philip Boyle Smith, Yuji Tachikawa
For a 2d gauged sigma model with target space and discrete gauge group , we consider a generalisation of Vafa's discrete torsion that assigns different local…
Bosonisation Cohomology: Spin Structure Summation in Every Dimension
Philip Boyle Smith, Joe Davighi
Gauging fermion parity and summing over spin structures are subtly distinct operations. We introduce 'bosonisation cohomology' groups to capture this difference, for…
Backfiring Bosonisation
Philip Boyle Smith, Yunqin Zheng
For a fermionic quantum field theory in dimensions, there is a subtle difference between summing over spin structures and gauging . If the gravitational anomaly van…
