Laser-ion acceleration through controlled surface contamination
(The American Institute of Physics, 2011-04)
Disentanglement and decoherence without dissipation at non-zero temperatures
(2010-09)
Decoherence is well understood, in contrast with disentanglement. According to common lore, irreversible coupling to a dissipative environment is the mechanism for loss of entanglement. Here, we show that, on the contrary, ...
What Turns Galaxies Off? The Different Morphologies of Star-forming and Quiescent Galaxies since z ~ 2 from CANDELS
(IOP Publishing, 2012)
We use HST /WFC3 imaging from the CANDELS Multi-Cycle Treasury Survey, in conjunction with the Sloan Digital Sky Survey, to explore the evolution of galactic structure for galaxies with stellar masses >3 √ó 10 10 M ...
A doublet microlens array for imaging micron-sized objects
(IOP Publishing, 2011)
We present a high-numerical aperture, doublet microlens array for imaging micron-sized objects. The proposed doublet architecture consists of glass microspheres trapped on a predefined array of silicon microholes and covered ...
Oblique radiative shocks, including their interactions with nonradiative polytropic shocks
(The American Institute of Physics, 2011-05)
Prof. von Jolly’s 1878 prediction of the end of theoretical physics as reported by Max Planck
(2016-03-06)
It is provided here the original German and an English translation of a passage from a 1924 essay by Max Planck that reports a prediction of the end of theoretical physics expressed to him by one of his esteemed physics ...
Monte Carlo investigations of the effect of beam divergence on thick, segmented crystalline scintillators for radiotherapy imaging
(2010-07)
The use of thick, segmented scintillators in electronic portal imagers offers the potential for significant improvement in x-ray detection efficiency compared to conventional phosphor screens. Such improvement substantially ...
Plasmonic backscattering enhanced inverted photovoltaics
(The American Institute of Physics, 2011-09)
The Disk-wind-Jet Connection in the Black Hole H 1743-322
(IOP Publishing, 2012)
X-ray disk winds are detected in spectrally soft, disk-dominated phases of stellar-mass black hole outbursts. In contrast, compact, steady, relativistic jets are detected in spectrally hard states that are dominated by ...
X-Ray Spectral Variability in NGC 3783
(IOP Publishing, 2012)
NGC 3783 was observed for approximately 210 ks by Suzaku and in this time showed significant spectral and flux variability at both short (20 ks) and long (100 ks) timescales. The full observation is found to consist of ...
