A single atom in free space as a quantum aperture
The resonant absorption cross section for a single twostate atom in free space driven by an electromagnetic field of wavelength λ is σ = 3λ/2π [1]. Thus it seems reasonable to assume that a “weak” incident light beam focused onto an area A ∼ σ would experience a loss (as resonance fluorescence) comparable to the incident energy of the beam itself and would, for off-resonant excitation, suffer a...
متن کاملSingle atom in free space as a quantum aperture
We calculate exact three-dimensional solutions of Maxwell equations corresponding to strongly focused light beams, and study their interaction with a single atom in free space. We show how the naive picture of the atom as an absorber with a size given by its radiative cross section s53l/2p must be modified. The implications of these results for quantum-information-processing capabilities of tra...
متن کاملControllable optical phase shift over one radian from a single isolated atom.
Fundamental optics such as lenses and prisms work by applying phase shifts of several radians to incoming light, and rapid control of such phase shifts is crucial to telecommunications. However, large, controllable optical phase shifts have remained elusive for isolated quantum systems. We have used a single trapped atomic ion to induce and measure a large optical phase shift of 1.3±0.1 radians...

15 صفحه اول0 Scattering Theory of Kondo Mirages and Observation of Single Kondo Atom Phase Shift
We explain the origin of the Kondo mirage seen in recent quantum corral Scanning Tunneling Microscope (STM) experiments with a scattering theory of electrons on the surfaces of metals. Our theory combined with experimental data provides the first direct observation of a single Kondo atom phase shift. The Kondo mirage observed at the empty focus of an elliptical quantum corral is shown to arise ...
