Reducing the electric field sensitivity of a Rydberg state transition by the application of a non-resonant microwave field
(University of Waterloo, 2013-01-23)The 87Rb 49s->48s Rydberg state transition was rendered insensitive to electric field fluctuations about a 1V/cm dc electric field. This was accomplished by applying a non-resonant 38.445GHz microwave field to modify the ... -
Reduction of polymer surface tension by crystallized polymer nanoparticles
(AIP Publishing, 2010-10-14)Self-consistent field theory is applied to investigate the effects of crystallized polymer nanoparticles on polymer surface tension. It is predicted that the nanoparticles locate preferentially at the polymer surface and ... -
Reference Frames and Algorithms for Quantum Information Processing
(University of Waterloo, 2009-08-27)The main results of this thesis fall in to two areas, firstly quantum reference frames as a resource for quantum computations and secondly quantum algorithms. The results relating to quantum references consider their scaling ... -
The Relationship Between Active Galactic Nuclei and Metal-enriched Outflows in Galaxy Clusters
(University of Waterloo, 2012-01-25)Clusters of galaxies are host to powerful Active Galactic Nuclei (AGN) that greatly affect the thermal history of clusters. By keeping X-ray emitting gas from cooling, massive, run away star formation does not occur in the ... -
