Scalable ion traps for quantum information processing (2009)
Amini, J. M., Uys, H., Wesenberg, J. H., Seidelin, S., Britton, J., Bollinger, J. J., ...
We report on the design, fabrication, and preliminary testing of a 150 zone array built in a `surface-electrode' geometry microfabricated on a single substrate. We demonstrate transport of atomic...
Superradiant Raman scattering in an ultracold Bose gas at finite temperature (2008)
We study superradiant Raman scattering from an ultra-cold, but finite temperature Bose gas in a harmonic trap. Numerical simulations indicate the existence of distinct timescales associated with the...
Optomechanical trapping and cooling of partially transparent mirrors (2007)
Bhattacharya, M., Uys, H., Meystre, P.
We consider the radiative trapping and cooling of a partially transmitting mirror suspended inside an optical cavity, generalizing the case of a perfectly reflecting mirror previously considered [M....
Quantum states for Heisenberg-limited interferometry (2007)
The phase resolution of interferometers is limited by the so-called Heisenberg limit, which states that the optimum phase sensitivity is inversely proportional to the number of interfering particles...
Theory of Coherent Raman Superradiance Imaging of Condensed Bose Gases (2006)
We model the off-resonant superradiant Raman scattering of light from a cigar-shaped atomic Bose-Einstein condensate. Absorption images of transmitted light serve as a direct probe of long range...
Quantum optics of ultra-cold molecules (2005)
Meiser, D., Miyakawa, T., Uys, H., Meystre, P.
Quantum optics has been a major driving force behind the rapid experimental developments that have led from the first laser cooling schemes to the Bose-Einstein condensation (BEC) of dilute atomic...
Fluctuations in the formation time of ultracold dimers from fermionic atoms (2004)
Uys, H., Miyakawa, T., Meiser, D., Meystre, P.
We investigate the temporal fluctuations characteristic of the formation of molecular dimers from ultracold fermionic atoms via Raman photoassociation. The quantum fluctuations inherent to the...
Generalized Statistics and High Tc Superconductivity (2001)
Uys, H., Miller, H. G., Khanna, F. C.
Introducing the generalized, non-extensive statistics proposed by Tsallis[1988], into the standard s-wave pairing BCS theory of superconductivity in 2D yields a reasonable description of many of the...
Generalized Statistics and the Fluctuation-Dissipation Theorem (2001)
If the generalized statistics suggested by Tsallis are used in statistical mechanics, the fluctuation-dissipation theorem no longer holds. Only in the limiting case where Boltzmann statistics are...
