Cosmological Dynamics of the Thermal Scalar Near the Hagedorn Temperature
Arnab Pradhan, Luis Rufino, Scott Watson
We study the cosmological dynamics of the thermal scalar the winding string mode that becomes massless at the Hagedorn transition by coupling it to the string-frame gravi dilaton e…
Cosmological Perturbations from a New Approach to Inflation
Brandon Melcher, Arnab Pradhan, Scott Watson
In a previous paper we proposed a new approach to the beginning of inflation -- a lingering universe. The universe begins in a lingering state with a nearly vanishing Hubble parame…
Generalized Models for Inflationary Preheating: Oscillations and Symmetries
Leia Barrowes, Fred C. Adams, Anthony M. Bloch +2
The paradigm of the inflationary universe provides a possible explanation for several observed cosmological properties. In order for such solutions to be successful, the universe m…
Waiting for Inflation: A New Initial State for the Universe
Brandon Melcher, Arnab Pradhan, Scott Watson
We propose a cosmological lingering phase for the initial state prior to inflation which would help address the singularity problem of inflation. The universe begins with a constan…
