Kavli Affiliate: Tom Melia | First 5 Authors: Weiguang Cao, Xiaochuan Lu, Tom Melia, , | Summary: We identify constraints in the energy spectra of quantum theories that have a global $O(N)$ symmetry, where $N$ is treated as a continuous parameter. We point out that a class of evanescent states fall out of the spectrum […]
