The Unitarity Flow Conjecture: An On-shell Approach to the Renormalization Group
Ameya Chavda, Daniel McLoughlin, Sebastian Mizera +1
We propose that the broad architecture of the renormalization group flow in quantum field theories is, at least in part, fixed by unitarity. The precise statement is summarized in…
The Unitary Architecture of Renormalization
Ameya Chavda, Daniel McLoughlin, Sebastian Mizera +1
We set up a bootstrap problem for renormalization. Working in the massless four-dimensional O model and the theory, we prove that unitarity leads to all-loop recursio…
Hadamard tails from flat-space perturbation theory
Ameya Chavda, Alberto Nicolis, Alessandro Podo +1
The short-distance singular structure of the two-point function of a free scalar field in curved spacetime has a universal behavior that characterizes well-behaved states (called H…
Fractonic Coset Construction for Spontaneously Broken Translations
Ameya Chavda, Daniel Naegels, John Staunton
We study the homogeneous breaking of spatial translation symmetry concomitantly with the spontaneous breaking of other internal and spacetime symmetries, including dilations. We us…
