A is the ANEC

12.10.2023 10:00 – 11:00

I will describe a connection between the Averaged Null Energy Condition (ANEC) and the monotonicity of the renormalization group that is obtained by studying light-ray operators in quantum field theories that flow between two conformal fixed points. In 2d, this provides a new proof of the c-theorem that is based on matching anomalies in the stress-tensor 3-point function and relies on special properties of light-ray operators. If time permits, I will also illustrate the 4d case, where we obtain another proof of the a-theorem.
