Non-local charges from perturbed defects via SymTFT in 2d CFT
Federico Ambrosino, Ingo Runkel, Gérard M. T. Watts
We investigate non-local conserved charges in perturbed two-dimensional conformal field theories from the point of view of the 3d SymTFT of the unperturbed theory. In the SymTFT we…

Modular symmetry of massive free fermions
Max Downing, Sameer Murthy, Gerard M. T. Watts
We construct an infinite set of conserved tensor currents of rank , , in the two-dimensional theory of free massive fermions, which are bilinear in the fermionic f…
