Physical consequences of the QED theta angle
Stephen D. H. Hsu
We describe a simple gedanken experiment which illustrates the physical effects of the QED theta angle, a fundamental parameter of Nature that has yet to be measured. The effects a…
Nonlinear Psychometric Thresholds for Physics and Mathematics
Stephen D. H. Hsu, James Schombert
We analyze 5 years of student records at the University of Oregon to estimate the probability of success (as defined by superior undergraduate record; sufficient for admission to g…
Asymptotic Safety, Singularities, and Gravitational Collapse
Roberto Casadio, Stephen D. H. Hsu, Behrouz Mirza
Asymptotic safety (an ultraviolet fixed point with finite-dimensional critical surface) offers the possibility that a predictive theory of quantum gravity can be obtained from the…
White holes and eternal black holes
Stephen D. H. Hsu
We investigate isolated white holes surrounded by vacuum, which correspond to the time reversal of eternal black holes that do not evaporate. We show that isolated white holes prod…
Dark Energy, with Signatures
Sourish Dutta, Stephen D. H. Hsu, Robert J. Scherrer
We propose a class of simple dark energy models which predict a late-time dark radiation component and a distinctive time-dependent equation of state for redshift . T…
The black hole information paradox and macroscopic superpositions
Stephen D. H. Hsu
We investigate the experimental capabilities required to test whether black holes destroy information. We show that an experiment capable of illuminating the information puzzle mus…
