Quantization of the massless minimally coupled scalar field and the dS/CFT correspondence
Andrew J. Tolley, Neil Turok
We consider the quantization of the massless minimally coupled scalar field in de Sitter spacetime. The no-boundary Euclidean prescription naturally picks out the de Sitter invaria…
Detecting magnetic CMB polarization on an incomplete sky
Antony Lewis, Anthony Challinor, Neil Turok
The full sky cosmic microwave background polarization field can be decomposed into `electric' and `magnetic' components. Working in harmonic space we construct magnetic variables t…
The shapes of dark matter dominated dwarf spheroidal stellar density profiles
Kris Sigurdson, Neil Turok
A Bayesian likelihood analysis of the stellar density profile shapes of several dark matter dominated Galactic dwarf spheroidal galaxies (dSphs) has been completed. This analysis i…
A Brief Comment on "The Pyrotechnic Universe"
Justin Khoury, Burt A. Ovrut, Paul J. Steinhardt +1
We respond to the criticisms by Kallosh, Kofman and Linde concerning our proposal of the ekpyrotic universe scenario. We point out a number of errors in their considerations and ar…
Comment on `Quantum Creation of an Open Universe', by Andrei Linde
S. W. Hawking, Neil Turok
We comment on Linde's claim that one should change the sign in the action for a Euclidean instanton in quantum cosmology, resulting in the formula for the probabili…
A Technique for Calculating Quantum Corrections to Solitons
Chris Barnes, Neil Turok
We present a numerical scheme for calculating the first quantum corrections to the properties of static solitons. The technique is applicable to solitons of arbitrary shape, and ma…
