Abstract:
We discuss the gross thermodynamical properties of brane-worlds with a focus on the Randall-Sundrum scenarios. We argue that the Gibbons-Hawking effect and the Hawking-Page phase transitions are both realized in these five dimensional brane world models, and hence they may both play a role in early universe cosmology. This could be particularly interesting during an de-Sitter phase associated with cosmic inflation, where thermal effects are responsible for the perturbations created.
