Bound States in Perturbative Quantum Gravity with Hydrogen-like Degeneracy
Callum R. T. Jones, Shruti Paranjape, Marcos Skowronek
Recent results in the study of gravitational scattering amplitudes indicate that some highly-symmetric relativistic systems may exactly conserve a version of the Laplace-Runge-Lenz…
Classical Spin Transitions and Absorptive Scattering
Juan Pablo Gatica, Callum R. T. Jones
We describe an on-shell, amplitudes-based approach to incorporating radiation absorption effects in the post-Minkowskian scattering of generic, compact, spinning bodies. Classical…
Constraints on Long-Range Forces in De Sitter Space
Daniel Baumann, Kurt Hinterbichler, Callum R. T. Jones +4
The representation theory of de Sitter space admits partially massless (PM) particles, but whether such particles can participate in consistent interacting theories remains unclear…
Smooth Splitting and Zeros from On-Shell Recursion
Callum R. T. Jones, Shruti Paranjape
We describe a new approach to understanding the origins of recently discovered "hidden zeros" and "smooth splitting" of tree-level amplitudes in , Non-Linear Sigma Mo…
Absorptive Effects and Classical Black Hole Scattering
Callum R. T. Jones, Michael S. Ruf
We describe an approach to incorporating the physical effects of the absorption of energy by the event horizon of black holes in the scattering amplitudes based post-Minkowskian, p…
Classical Dynamics of Vortex Solitons from Perturbative Scattering Amplitudes
Callum R. T. Jones
We introduce a novel point-particle effective description of ANO vortex solitons in the critical Abelian Higgs Model (AHM) in based on the small winding expansion. Identify…
