Gravitational wave generation from bubble collisions in first-order phase transitions: an analytic approach
Chiara Caprini, Ruth Durrer, Geraldine Servant
Gravitational wave production from bubble collisions was calculated in the early nineties using numerical simulations. In this paper, we present an alternative analytic estimate, r…
Generalized Einstein-Aether theories and the Solar System
Camille Bonvin, Ruth Durrer, Pedro G. Ferreira +2
It has been shown that generalized Einstein-Aether theories may lead to significant modifications to the non-relativistic limit of the Einstein equations. In this paper we study th…
Superluminal motion and closed signal curves
Camille Bonvin, Chiara Caprini, Ruth Durrer
We discuss some properties of Lorentz invariant theories which allow for superluminal motion. We show that, if signals are always sent forward in time, closed curves along which si…
Dynamical Casimir effect for gravitons in bouncing braneworlds
Marcus Ruser, Ruth Durrer
We consider a two-brane system in a five-dimensional anti-de Sitter spacetime. We study particle creation due to the motion of the physical brane which first approaches the second…
The dynamical Casimir effect in braneworlds
Ruth Durrer, Marcus Ruser
In braneworld cosmology the expanding Universe is realized as a brane moving through a warped higher-dimensional spacetime. Like a moving mirror causes the creation of photons out…
