Effective Field Theory for Extreme Mass Ratios
Clifford Cheung, Julio Parra-Martinez, Ira Z. Rothstein +2
We derive an effective field theory describing a pair of gravitationally interacting point particles in an expansion in their mass ratio, also known as the self-force (SF) expansio…
Bespoke Dual Resonance
Clifford Cheung, Grant N. Remmen
Dual resonance is one of the great miracles of string theory. At a fundamental level, it implies that the particles exchanged in different channels are subtly equivalent. Furthermo…
On Entropy Growth in Perturbative Scattering
Clifford Cheung, Temple He, Allic Sivaramakrishnan
Inspired by the second law of thermodynamics, we study the change in subsystem entropy generated by dynamical unitary evolution of a product state in a bipartite system. Working at…
Stringy Dynamics from an Amplitudes Bootstrap
Clifford Cheung, Grant N. Remmen
We describe an analytic procedure whereby scattering amplitudes are bootstrapped directly from an input mass spectrum and a handful of physical constraints: crossing symmetry, boun…
