Random Functions via Dyson Brownian Motion: Progress and Problems
Gaoyuan Wang, Thorsten Battefeld
We develope a computationally efficient extension of the Dyson Brownian Motion (DBM) algorithm to generate random function in C2 locally. We further explain that random functions g…
Vacuum Selection on Axionic Landscapes
Gaoyuan Wang, Thorsten Battefeld
We compute the distribution of minima that are reached dynamically on multi-field axionic landscapes, both numerically and analytically. Such landscapes are well suited for inflati…
The Anisotropic Line Correlation Function as a Probe of Anisotropies in Galaxy Surveys
Alexander Eggemeier, Thorsten Battefeld, Robert E. Smith +1
We propose an anisotropic generalisation of the line correlation function (ALCF) to separate and quantify phase information in the large-scale structure of galaxies. The line corre…
Local random potentials of high differentiability to model the Landscape
Thorsten Battefeld, Chirag Modi
We generate random functions locally via a novel generalization of Dyson Brownian motion, such that the functions are in a desired differentiability class, while ensuring that the…
A Universal Bound on Excitations of Heavy Fields during Inflation
Thorsten Battefeld, R. C. Freitas
We discuss a universal bound on any excitation of heavy fields during inflation: the ratio of the heavy field's energy density to the one driving inflation must be less than the ma…
Particle Production during Inflation in Light of PLANCK
Diana Battefeld, Thorsten Battefeld, Daniel Fiene
We consider trapped inflation in a higher dimensional field space: particle production at a dense distribution of extra species points leads to a terminal velocity at which inflati…
