Irreversibility in quantum field theories with boundaries

Irreversibility in quantum field theories with boundaries

Abstract We study conformal field theories with boundaries, and their boundary renormalization group (RG) flows, using methods from quantum information theory. Positivity of the relative entropy, together with unitarity and Lorentz invariance, give rise to bounds that characterize the irreversibilit...
