Null energy constraints on two-dimensional RG flows

Null energy constraints on two-dimensional RG flows

Abstract We study applications of spectral positivity and the averaged null energy condition (ANEC) to renormalization group (RG) flows in two-dimensional quantum field theory. We find a succinct new proof of the Zamolodchikov c-theorem, and derive further independent constraints along the flow. In...
