Robust optimization of adiabatic tapers for coupling to slow-light photonic-crystal waveguides
Tapered structure coupling photonic crystal waveguides candles nano
2015/8/7
We investigate the design of taper structures for coupling to slow-light modes of various photonic-crystal waveguides while taking into account parameter uncertainties inherent in practical fabricatio...
Gravitational Wave Production through Decay of the Inflaton into Intermediary Fields During Slow Roll Inflation
Gravitational Wave Intermediary Fields Slow Roll Inflation
2014/11/20
This dissertation looks for possible observable signals of tensor metric perturbations sourced during slow roll inflation from decay of the inflaton field into other intermediary fields. We focus on t...

Controllable ultra-broadband slow light Rubidium vapor Optics
2011/8/18
Abstract: We study ultra-broadband slow light in a warm Rubidium vapor cell. By working between the D1 and D2 transitions, we find a several-nm window centered at 788.4 nm in which the group index is ...

Abstract: Approximate probabilities of formation of various atoms and ions in different bound states are determined for the exothermic nuclear $(n,{}^{6}$Li$;t,{}^{4}$He)-reaction of atomic lithium-6 ...
The EIT waves [named after the Extreme-ultraviolet Imaging Telescope (EIT) onboard the Solar and Heliospheric Observatory (SOHO)] are in the literature
usually described as fast magneto-acoustic (FMA...

slow roll inflation loop quantum cosmology
2010/12/27
We consider the measure problem in standard slow-roll inflationary models from the perspective of loop quantum cosmology (LQC). Following recent results by Ashtekar and Sloan, we study the probabilit...

slow samples Sherrington-Kirkpatrick model
2010/11/23
Using results of a Monte Carlo simulation of the Sherrington-Kirkpatrick model, we try to charac-terize the slow disorder samples, namely we analyze visually the correlation between the relaxation tim...
We observed slow moving vortex lattices in NbSe2 using a home built STM at a temperature of
