Gravitational Waves from Long Strings and Loops
Christos Litos, Sarunas Verner, Wei Xue +1
We compute the gravitational wave spectrum produced by a global cosmic string network in the scaling regime. The spectrum naturally divides at the string correlation length into in…
Sensing the Inflationary Production of Scalars
A. J. Foraci, C. Litos, R. P. Woodard
We review the mechanism by which loops of matter fields contribute to the graviton self-energy during de Sitter inflation. The self-energy is used to quantum-correct the linearized…
Axion strings from string axions
James M. Cline, Christos Litos, Wei Xue
A favored scenario for axions to be dark matter is for them to form a cosmic string network that subsequently decays, allowing for a tight link between the axion mass and relic abu…
Holographic RG flows on Squashed
Elias Kiritsis, Christos Litos
Holographic RG flows dual to QFTs on a squashed are considered in the framework of Einstein dilaton gravity in four dimensions. A general dilaton potential is used and flows…
