Hawking Amplitudes: Subtle Points About Saddle Points
Owen Lear, Daniel McLoughlin, Sebastian Mizera +1
Hawking amplitudes provide a new way of determining the Hawking spectrum of black holes, using on-shell techniques borrowed from the literature on scattering amplitudes. In this pa…
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…
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…
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…
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…
Applications of de Sitter Causality Conditions
Daniel McLoughlin, Rachel A Rosen
We find explicit de Sitter shockwave solutions in arbitrary spacetime dimensions. We use these to determine the dimensional-dependent "stretching" of the de Sitter Penrose diagram…
