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…

Positivity and Fermionic Dense Matter

Deog Ki Hong, Stephen D. H. Hsu

Euclidean dense matter generically suffers from the fermion sign problem. However, we argue that the sign problem is absent if one considers only low-energy degrees of freedom. Spe…

Global Spread of Infectious Diseases

S. Hsu, A. Zee

We develop simple models for the global spread of infectious diseases, emphasizing human mobility via air travel and the variation of public health infrastructure from region to re…

The QCD Phase Diagram and Explosive Astrophysics

Stephen D. H. Hsu

I give a brief overview of our current understanding of the QCD phase diagram at finite temperature and baryon density. I emphasize phase transitions which occur at high density an…
