Probing the origin of our Universe through cosmic microwave background constraints on gravitational waves
Sarah Shandera, Peter Adshead, Mustafa Amin +16
The next generation of instruments designed to measure the polarization of the cosmic microwave background (CMB) will provide a historic opportunity to open the gravitational wave…
Slow Roll Reconstruction: Constraints on Inflation from the 3 Year WMAP Dataset
Hiranya Peiris, Richard Easther
We study the constraints on the inflationary parameter space derived from the 3 year WMAP dataset using ``slow roll reconstruction'', using the SDSS galaxy power spectrum to gain f…
Alternative Numerical Techniques
G. S. Guralnik, J. Doll, R. Easther +5
Two new approaches to numerical QFT are presented.
Numerical Quantum Field Theory on the Continuum and a New Look at Perturbation Theory
P. Emirdag, R. Easther, G. S. Guralnik +2
The Source Galerkin method finds approximate solutions to the functional differential equations of field theories in the presence of external sources. While developing this process…
New Numerical Methods for Quantum Field Theories on the Continuum
P. Emirdag, R. Easther, G. S. Guralnik +1
The Source Galerkin Method is a new numerical technique that is being developed to solve Quantum Field Theories on the continuum. It is not based on Monte Carlo techniques and has…
Vacuum fluctuations in axion-dilaton cosmologies
E. J. Copeland, Richard Easther, David Wands
We study axion-dilaton cosmologies derived from the low-energy string effective action. We present the classical homogeneous Friedmann-Robertson-Walker solutions and derive the sem…
