Gravity limits the kinetic energy of a massive elementary particle
Justin C. Feng
In this note, I argue that tidal effects generically limit the kinetic energy of a single massive elementary particle in the vicinity of a compact object. As the kinetic energy is…

Smooth metrics can hide thin shells
Justin C. Feng
In this note, I consider a class of metric tensors with smooth components that naively appear to describe dynamical wormholes with vanishing spacetime curvature. I point out that t…

Regularizing Dual-Frame Generalized Harmonic Gauge at Null Infinity
Miguel Duarte, Edgar Gasperín, Justin C. Feng +1
The dual-frame formalism leads to an approach to extend numerical relativity simulations in generalized harmonic gauge (GHG) all the way to null infinity. A major setback is that w…
