Lightsheets, Branes and the Covariant Entropy Bound
Deog Ki Hong, Stephen D. H. Hsu
We investigate the geometry of lightsheets comprised of null geodesics near a brane. Null geodesics which begin parallel to a brane a distance d away are typically gravitationally…
Anthropic Distribution for Cosmological Constant and Primordial Density Perturbations
Michael L. Graesser, Stephen D. H. Hsu, Alejandro Jenkins +1
The anthropic principle has been proposed as an explanation for the observed value of the cosmological constant. Here we revisit this proposal by allowing for variation between uni…
Brane World Confronts Holography
Deog Ki Hong, Stephen D. H. Hsu
Holography principle imposes a stringent constraint on the scale of quantum gravity in brane-world scenarios, where all matter is confined on the brane. The thermodynamic ent…
On Spherically Symmetric Breathers in Scalar Theories
James N. Hormuzdiar, Stephen D. H. Hsu
We develop an algorithm which can be used to exclude the existence of classical breathers (periodic finite energy solutions) in scalar field theories, and apply it to several cases…
