Inflationary Cosmology, Diffeomorphism Group of the Line and Virasoro Coadjoint Orbits
James E. Lidsey
The cosmological field equations sourced by a self-interacting scalar field are dynamically equivalent to a closed system of equations obtained by applying the moment method to non…
Holographic Cosmology from the First Law of Thermodynamics and the Generalized Uncertainty Principle
James E. Lidsey
The cosmological Friedmann equation sourced by the trace anomaly of a conformal field theory that is dual to the five-dimensional Schwarzschild-AdS geometry can be derived from the…
Non-relativistic Matrix Inflation
Aaron Berndsen, James. E. Lidsey, John Ward
We reconsider a string theoretic inflationary model, where inflation is driven by multiple coincident -branes in the finite limit. We show that the finite action ca…
Gravitational Wave Constraints on Multi-Brane Inflation
Ian Huston, James E. Lidsey, Steven Thomas +1
A class of non-canonical inflationary models is identified, where the leading-order contribution to the non-Gaussianity of the curvature perturbation is determined by the sound spe…
Scaling Cosmologies from Duality Twisted Compactifications
James E. Lidsey, Karim A. Malik
Oscillating moduli fields can support a cosmological scaling solution in the presence of a perfect fluid when the scalar field potential satisfies appropriate conditions. We examin…
Gravitational Wave Constraints on DBI Inflation
James E. Lidsey, Ian Huston
An upper bound on the amplitude of the primordial gravitational wave spectrum generated during ultra-violet DBI inflation is derived. The bound is insensitive to the form of the in…
