Generating Non-Gaussian Adiabatic Fluctuations from Inflation
D. S. Salopek
As the quality of cosmological data continue to improve, it is natural to test the statistics of primordial fluctuations: are they Gaussian or non-Gaussian? I review a model which…
Initial Hypersurface Formulation: Hamilton-Jacobi Theory for Strongly Coupled Gravitational Systems
D. S. Salopek
Strongly coupled gravitational systems describe Einstein gravity and matter in the limit that Newton's constant G is assumed to be very large. The nonlinear evolution of these syst…
Hamilton-Jacobi Solutions for Strongly-Coupled Gravity and Matter
D. S. Salopek
A Green's function method is developed for solving strongly-coupled gravity and matter in the semiclassical limit. In the strong-coupling limit, one assumes that Newton's constant…
Coordinate-free Solutions for Cosmological Superspace
D. S. Salopek
Hamilton-Jacobi theory for general relativity provides an elegant covariant formulation of the gravitational field. A general `coordinate-free' method of integrating the functional…
Cosmological Inflation and the Nature of Time
D. S. Salopek
Recent advances in observational cosmology are changing the way we view the nature of time. In general relativity, the freedom in choosing a time hypersurface has hampered the impl…
The Role of Time in Physical Cosmology
