Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Nathan Benjamin, Hirosi Ooguri, Shu-Heng Shao, Yifan Wang, | Summary: We show that every compact, unitary two-dimensional CFT with an abelian conserved current has vanishing twist gap for charged primary fields with respect to the $mathfrak{u}(1)times$Virasoro algebra. This means that either the chiral algebra is enhanced by […]
