Evolution of Generic Varying-Tension Cosmic Strings in Expanding Spacetimes
Hubert Lau Sze Chun, Joseph Conlon
It has recently been realised that strings with time-dependent tensions exhibit interesting dynamics; in particular, when the tension decreases loops of string can grow and possibl…
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…
A Note on 4d Kination and Higher-Dimensional Uplifts
Fien Apers, Joseph P. Conlon, Martin Mosny
This note expands on the details of the relationship between 4d kination solutions in string cosmology and Kasner solutions of 10d general relativity. It extends previous analyses…
Percolating Cosmic String Networks from Kination
Joseph P. Conlon, Edmund J. Copeland, Edward Hardy +1
We describe a new mechanism, whose ingredients are realised in string compactifications, for the formation of cosmic (super)string networks. Oscillating string loops grow when thei…
String Theory and the Early Universe: Constraints and Opportunities
Joseph P. Conlon
This is a short account, based on a talk given at the 2024 Moriond Cosmology Conference, of where and why string theory matters in early universe cosmology. It is written for a cos…
String Theory and the First Half of the Universe
Fien Apers, Joseph P. Conlon, Edmund J. Copeland +2
We perform a detailed study of stringy moduli-driven cosmologies between the end of inflation and the commencement of the Hot Big Bang, including both the background and cosmologic…
