Does QFT make sense in non-integer dimensions?
Diego Delmastro, Yan-Yan Li, Dikshant Rathore
We revisit the old problem of analytically continuing QFTs to fractional dimension . We observe that common theories like QCD and QED have branch cuts in the complex…

Non-Local Conserved Currents and Continuous Non-Invertible Symmetries
Diego Delmastro, Adar Sharon, Yunqin Zheng
We embark on a systematic study of continuous non-invertible symmetries, focusing on 1+1d CFTs. We describe a generalized version of Noether's theorem, where continuous non-inverti…

Global Anomalies on the Hilbert Space
Diego Delmastro, Davide Gaiotto, Jaume Gomis
We show that certain global anomalies can be detected in an elementary fashion by analyzing the way the symmetry algebra is realized on the torus Hilbert space of the anomalous the…
