High-frequency Gravitational Waves from Superstring Phases in the Early Universe
Joseph P. Conlon, Edmund J. Copeland, Edward Hardy +1
When moduli roll in the early universe, all physical scales - including string tensions - simultaneously evolve. The dynamics of cosmic string loops with time-varying tension can p…
Self-Tracking Solutions for Asymptotic Scalar Fields
Martin Mosny, Joseph P. Conlon, Edmund J. Copeland
We explore the dynamics of pure scalar fields rolling on an exponential potential in the absence of any additional background fluid and demonstrate the existence of self-tracking s…
Dynamical Systems and Superstring Phases in the Early Universe
Noelia Sánchez González, Joseph P. Conlon, Edmund J. Copeland +1
We study the string theory dynamics of the volume scalar rolling down an exponential potential during the period between inflation and reheating, in a background of cosmic superstr…
