The Ekpyrotic Universe: Colliding Branes and the Origin of the Hot Big Bang
Justin Khoury, Burt A. Ovrut, Paul J. Steinhardt +1
We propose a cosmological scenario in which the hot big bang universe is produced by the collision of a brane in the bulk space with a bounding orbifold plane, beginning from an ot…
Sailing through the big crunch-big bang transition
Itzhak Bars, Paul Steinhardt, Neil Turok
In a recent series of papers, we have shown that theories with scalar fields coupled to gravity (e.g., the standard model) can be lifted to a Weyl-invariant equivalent theory in wh…
Characterising the Primordial Cosmic Perturbations
Martin Bucher, Kavilan Moodley, Neil Turok
The most general homogeneous and isotropic statistical ensemble of linear scalar perturbations which are regular at early times, in a universe with only photons, baryons, neutrinos…
Electroweak Baryogenesis from a Classical Force
Michael Joyce, Tomislav Prokopec, Neil Turok
We describe a new effect which produces baryons at a first order electroweak phase transition. It operates when there is a CP-violating field present on propagating bubble walls. T…
Fixed points of classical gravity coupled with a Standard-Model-like theory
Latham Boyle, Neil Turok, Vatsalya Vaibhav
Coupling quantum field theory (QFT) \!-\! even free QFT \!-\! to gravity leads to well-known problems. In particular, the stress tensor (gravity's source) and its correl…
Perfect Quantum Cosmological Bounce
Steffen Gielen, Neil Turok
We study quantum cosmology with conformal matter comprising a perfect radiation fluid and a number of conformally coupled scalar fields. Focusing initially on the collective coordi…
