Quantum jumps and spin dynamics of interacting atoms in a strongly coupled atom-cavity system
Quantum jumps spin dynamics atoms strongly coupled atom-cavity system
2010/4/9
We experimentally investigate the spin dynamics of one and two neutral atoms strongly coupled to a high finesse optical cavity. We observe quantum jumps between hyperfine ground states of a single ato...
Single atoms have been spotted doing the quantum version of the random walk by physicists in Germany. This sighting of a “quantum walk” could help in the design of quantum search algorithms, or in the...
Energetic neutral atom fluxes from the heliosheath varying with the activity phase of the solar cycle
Energetic neutral atom fluxes solar cycle
2009/5/27
Energetic neutral atoms (ENA's) which are produced in the heliospheric interface can be used to remotely investigate this highly interesting, but poorly known region acting as buffer against the inter...

Intensity-field correlation of single-atom resonance fluorescence
Intensity-field single-atom resonance fluorescence
2010/4/9
We report measurements of an intensity-field correlation function of the resonance fluorescence of a single trapped Ba+ ion. Detection of a photon prepares the atom in its ground state and we observe ...
Properties of a two-level atom coupled to the quantized electromagnetic field at finite temperature are determined. The analysis is based on a new method (inspired by QED) of describing qubits, develo...
Towards a monolithic optical cavity for atom detection and manipulation
a monolithic optical cavity atom detection manipulation
2010/4/7
We study a Fabry-Perot cavity formed from a ridge waveguide on a AlGaAs substrate. We experimentally determined the propagation losses in the waveguide at 780 nm, the wavelength of Rb atoms. We have a...
Hemispheric average Cl atom concentration from 13C/12C ratios in atmospheric methane
Hemispheric average Cl atom concentration 13C/12C ratios atmospheric methane
2009/3/10
Methane is a significant atmospheric trace gas in the context of greenhouse warming and climate change. The dominant sink of atmospheric methane is the hydroxyl radical (OH). Recently, a mechanism for...

Fully quantum-mechanical analytic results for single-photon transport in a single-mode waveguide coupled to a whispering-gallery resonator interacting with a two-level atom
quantum-mechanical analytic single-photon single-mode waveguide whispering-gallery resonator a two-level atom
2010/4/9
We analyze the single-photon transport in a single-mode waveguide coupled to a whispering-gallery-type resonator interacting with a two-level atom. The single-photon transport properties such as the t...
Theory of single-photon transport in a single-mode waveguide coupled to a cavity containing a two-level atom
single-photon transport a single-mode waveguide two-level atom
2010/4/9
The single-photon transport in a single-mode waveguide, coupled to a cavity embedded with a two-leval atom is analyzed. The single-photon transmission and reflection amplitudes, as well as the cavity ...

Feshbach ultracold atom-molecule collisions
2010/4/9
We investigate the presence of Feshbach resonances in ultracold alkali-dialkali reactive collisions. Quantum scattering calculations are performed on a new Na_3 quartet potential energy surface. An an...
Efficient routing of single photons by one atom and a microtoroidal cavity
single photons atom microtoroidal cavity
2010/4/8
Single photons from a coherent input are efficiently redirected to a separate output by way of a fiber-coupled microtoroidal cavity interacting with individual Cesium atoms. By operating in an overcou...
Birefringence lens effects of atom ensemble enhanced by electromagnetically induced transparency
Birefringence lens effects of atom electromagnetically induced transparency
2010/4/12
We study the optic control for birefringence of a polarized light by an atomic ensemble with a tripod configuration, which is mediated by the electromagnetically induced transparency with a spatially ...
Atmospheric chemistry of trans-CF3CH=CHF: products and mechanisms of hydroxyl radical and chlorine atom initiated oxidation
