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 recursion…
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…
Ladder Symmetries of Higher Dimensional Black Holes
Roman Berens, Lam Hui, Daniel McLoughlin +2
We compute the ladder operators for static tidal perturbations to higher-dimensional black holes. These operators map between solutions of the relevant equation of motion at differ…
Geometric Symmetries for the Vanishing of the Black Hole Tidal Love Numbers
Roman Berens, Lam Hui, Daniel McLoughlin +2
We present a unified geometric perspective on the symmetries underlying the spin 0, 1 and 2 static perturbations around a Schwarzschild black hole. In all cases, the symmetries are…
