An Ultraviolet Finite Theory of Scalars
Francesco Calisto, Clifford Cheung
We construct a theory of scalars that is free of short-distance infinities to all orders in perturbation theory. Loop divergences are neutralized by momentum-dependent interactions…
Thermal Positivity
Clifford Cheung, Rachel A. Rosen
We argue that Lorentz invariance and unitarity impose sharp constraints on thermodynamic quantities. By relating thermal vacuum diagrams to forward scattering amplitudes, we derive…
On Perturbatively Dressed Observables
Clifford Cheung, Allic Sivaramakrishnan, Jordan Wilson-Gerow +1
A central lesson of gravity is that local observables are ill-defined. Coordinates themselves are a redundancy of description, so any particular point in spacetime is only meaningf…
