Gravitational Collider Physics
Daniel Baumann, Horng Sheng Chia, Rafael A. Porto +1
We study the imprints of new ultralight particles on the gravitational-wave signals emitted by binary black holes. Superradiant instabilities may create large clouds of scalar or v…

The Spectra of Gravitational Atoms
Daniel Baumann, Horng Sheng Chia, John Stout +1
We compute the quasi-bound state spectra of ultralight scalar and vector fields around rotating black holes. These spectra are determined by the gravitational fine structure consta…

Real-Time Corrections to the Effective Potential
Guilherme L. Pimentel, John Stout
Non-perturbatively generated effective potentials play an extremely useful and often critical role in string and inflationary model building. These potentials are typically compute…
