Spherically symmetric solutions in quasi-local Einstein-Weyl gravity
Johanna Borissova, Breno L. Giacchini, Aaron Held
Quantum-gravitational effective actions with higher-derivative and non-local operators are expected to regularize the singularities of general relativity. Here we focus on quasi-lo…
Global stability of ghostly field theories: Classical scattering in dimensions
Aaron Held
We review results on small-data global stability and highlight their applicability to classical interacting scalar fields with opposite-sign kinetic terms (ghosts). Further, we pre…
Ghostly interactions in (1+1) dimensional classical field theory
Cédric Deffayet, Aaron Held, Shinji Mukohyama +1
We investigate the classical stability of two coupled scalar fields with opposite-sign kinetic terms evolving in 1+1 dimensional Minkowski spacetime. In the first part, we characte…
Black-hole binaries and waveforms in Quadratic Gravity
Aaron Held, Hyun Lim
We report on the first numerical-relativity simulations of black-hole binaries that deviate from General Relativity due to quadratic-curvature corrections. Said theory of Quadratic…
