Weak Convergence Results for Multiple Generations of a Branching Process

James Kuelbs, Anand N. Vidyashankar

We establish limit theorems involving weak convergence of multiple generations of critical and supercritical branching processes. These results arise naturally when dealing with th…

The "Coulomb phase" in frustrated systems

Christopher L. Henley

The "Coulomb phase" is an emergent state for lattice models (particularly highly frustrated antiferromagnets) which have local constraints that can be mapped to a divergence-free "…

Equation of state effects in black hole-neutron star mergers

Matthew D. Duez, Francois Foucart, Lawrence E. Kidder +2

The merger dynamics of a black hole-neutron star (BHNS) binary is influenced by the neutron star equation of state (EoS) through the latter's effect on the neutron star's radius an…

On type I cascaded quadratic soliton compression in lithium niobate: Compressing femtosecond pulses from high-power fiber lasers

Morten Bache, Frank W. Wise

The output pulses of a commercial high-power femtosecond fiber laser or amplifier are typically around 300-500 fs with a wavelength around 1030 nm and 10s of J pulse energy. Her…

f-Vectors of Triangulated Balls

Samuel Kolins

We describe two methods for showing that a vector can not be the f-vector of a homology d-ball. As a consequence, we disprove a conjectured characterization of the f-vectors of bal…

Contact processes on random graphs with power law degree distributions have critical value 0

Shirshendu Chatterjee, Rick Durrett

If we consider the contact process with infection rate on a random graph on vertices with power law degree distributions, mean field calculations suggest that the critical…

Dante's Inferno

Marcus Berg, Enrico Pajer, Stefan Sjors

We present a simple two-field model of inflation and show how to embed it in string theory as a straightforward generalization of axion monodromy models. Phenomenologically, the pr…
