Challenges for String Gas Cosmology
Robert H. Brandenberger
In spite of the phenomenological successes of the inflationary universe scenario, the current realizations of inflation making use of scalar fields lead to serious conceptual probl…
On the Transfer of Metric Fluctuations when Extra Dimensions Bounce or Stabilize
T. J. Battefeld, S. P. Patil, R. H. Brandenberger
In this report, we study within the context of general relativity with one extra dimension compactified either on a circle or an orbifold, how radion fluctuations interact with met…
T-Duality and the Spectrum of Gravitational Waves
Paul Robert Chouha, Robert H. Brandenberger
In the inflationary universe scenario, the physical wavelength of cosmological fluctuation modes which are currently probed in observations was shorter than the Hubble radius, and…
Non-Perturbative Instabilities as a Solution of the Cosmological Moduli Problem
Natalia Shuhmaher, Robert Brandenberger
It is widely accepted that moduli in the mass range 10eV - GeV which start to oscillate with an amplitude of the order of the Planck scale either jeopardize successful predic…
Single Field Baryogenesis and the Scale of Inflation
K. R. S. Balaji, R. H. Brandenberger, Alessio Notari
In the context of inflationary cosmology, we discuss a minimal baryogenesis scenario in which the resulting baryon to entropy ratio is determined by the amplitude of the anisotropi…
Challenges for Inflationary Cosmology
Robert H. Brandenberger
Inflationary cosmology has provided a predictive and phenomenologically very successful scenario for early universe cosmology. Attempts to implement inflation using scalar fields,…
