Infinite Distances and Factorization
John Stout
The information metric provides a unique notion of distance along any continuous family of physical theories, placing two theories further apart the more distinguishable they are.…
Sharp Signals of Boson Clouds in Black Hole Binary Inspirals
Daniel Baumann, Gianfranco Bertone, John Stout +1
Gravitational waves (GWs) are an exciting new probe of physics beyond the standard models of gravity and particle physics. One interesting possibility is provided by the so-called…
Ionization of Gravitational Atoms
Daniel Baumann, Gianfranco Bertone, John Stout +1
Superradiant instabilities may create clouds of ultralight bosons around rotating black holes, forming so-called "gravitational atoms." It was recently shown that the presence of a…
Infinite Distance Limits and Information Theory
John Stout
The classical information metric provides a unique notion of distance on the space of probability distributions with a well-defined operational interpretation: two distributions ar…
Axion Mass from Magnetic Monopole Loops
JiJi Fan, Katherine Fraser, Matthew Reece +1
We show that axions interacting with abelian gauge fields obtain a potential from loops of magnetic monopoles. This is a consequence of the Witten effect: the axion field causes th…
Instanton Expansions and Phase Transitions
John Stout
A central object in any axionic theory is its periodic potential, which is typically generated by instantons. The goal of this paper is to understand what physically happens to the…
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…
Instanton Resummation and the Weak Gravity Conjecture
Ben Heidenreich, Cody Long, Liam McAllister +2
We develop methods for resummation of instanton lattice series. Using these tools, we investigate the consequences of the Weak Gravity Conjecture for large-field axion inflation. W…
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…
Runaway Relaxion Monodromy
Liam McAllister, Pedro Schwaller, Geraldine Servant +2
We examine the relaxion mechanism in string theory. An essential feature is that an axion winds over fundamental periods. In string theory realizations via axion monodrom…
Systematics of Axion Inflation in Calabi-Yau Hypersurfaces
Cody Long, Liam McAllister, John Stout
We initiate a comprehensive survey of axion inflation in compactifications of type IIB string theory on Calabi-Yau hypersurfaces in toric varieties. For every threefold with $h^{1,…
On Chiral Mesons in AdS/CFT
Liam McAllister, Paul McGuirk, John Stout
We analyze the spectra of non-chiral and chiral bifundamental mesons arising on intersecting D7-branes in . In the absence of magnetic flux on the curve of int…
