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…
