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…

Veneziano Variations: How Unique are String Amplitudes?

Clifford Cheung, Grant N. Remmen

String theory offers an elegant and concrete realization of how to consistently couple states of arbitrarily high spin. But how unique is this construction? In this paper we derive…

Non-perturbative Double Copy in Flatland

Clifford Cheung, James Mangan, Julio Parra-Martinez +1

We derive a non-perturbative, Lagrangian-level formulation of the double copy in two spacetime dimensions. Our results elucidate the field theoretic underpinnings of the double cop…
