Catastrophic Inflation in the Axiverse
Naomi Gendler, Oliver Janssen, Matthew Kleban +1
In the landscape of compactifications of type IIB string theory on O3/O7 orientifolds of Calabi--Yau threefolds, we identify regions of the axion potential in specific geometries t…
Source-Induced Reflection in Balanced Shallow-Water Networks
Binan Gu, Cameron Norton, Andre Nachbin
Width-balance conditions at a junction are often associated with reflectionless transmission, or transparency, in some one-dimensional wave models on networks. We show that, on cyc…
Accretion of Primordial Black Holes in Stellar Interiors
Matteo Cantiello, Ore Gottlieb, Cameron Norton +2
We study spherical accretion onto primordial black holes (PBHs) embedded in the core of a solar-type star. We compute the radiative efficiency self-consistently for the first time…
The Life and Death of Stars That Capture Primordial Black Holes
Ore Gottlieb, Matteo Cantiello, Cameron Norton +2
Primordial black holes (PBHs) in the asteroid mass window () remain viable dark matter candidates and can be captured by stars. We develop the first globa…
Tunneling from an oscillating initial state in quantum mechanics
Oliver Janssen, Matthew Kleban, Cameron Norton
We study the decay of general initial states out of a metastable potential well in quantum mechanics. We provide a closed-form expression for the probability current that tunnels t…
Monochromatic Mass Spectrum of Primordial Black Holes
Matthew Kleban, Cameron E. Norton
During slow-roll inflation, non-perturbative transitions can produce bubbles of metastable vacuum. These bubbles expand exponentially during inflation to super-horizon size, and la…
Cluster Cosmology Redux: A Compact Model of the Halo Mass Function
Cameron E. Norton, Fred C. Adams, August E. Evrard
Massive halos hosting groups and clusters of galaxies imprint coherent, arcminute-scale features across the spectrophotometric sky, especially optical-IR clusters of galaxies, dist…
Evolution of decaying particles and decay products in various scenarios for the future expansion of the universe
Cameron E. Norton, Robert J. Scherrer
We examine nonrelativistic particles that decay into relativistic products in big rip, little rip, and pseudo-rip models for the future evolution of the universe. In contrast to de…
The cosmological evolution of ultralight axionlike scalar fields
Cameron E. Norton, Robert J. Scherrer
We examine the cosmological evolution of ultralight axionlike (ULA) scalar fields with potentials of the form , with particular emphasis on the dev…
