Cooperative resonance linewidth narrowing in a planar metamaterial
Cooperative resonance linewidth planar metamaterial
2011/9/7
We theoretically analyze the experimental observations of a spectral line collapse in a metamaterial array of asymmetric split ring resonators [Fedotov et al., Phys. Rev. Lett. 104, 223901 (2010)].We ...
Coherent control of the cooperative branching ratio for nuclear x-ray pumping
Coherent control cooperative branching ratio nuclear x-ray pumping
2010/11/11
Coherent control of nuclear pumping in a three level system driven by x-ray light is investigated. In single nuclei, the pumping performance is determined by the branching ratio of the excited state p...
Cavity-enhanced atom detection with cooperative noise reduction
Cavity-enhanced atom detection cooperative noise reduction
2010/10/20
An optical microcavity with small mode radius is used to measure the local density of a cold
atom cloud. Atom densities below 1 per cavity mode volume are measured with signals near the
photon shot-...
