Interferometer-type structures for guided atoms.

We experimentally demonstrate interferometer-type guiding structures for neutral atoms based on dipole potentials created by microfabricated optical systems. As a central element we use an array of atom waveguides being formed by focusing a red-detuned laser beam with an array of cylindrical microlenses. Combining two of these arrays, we realize X-shaped beam splitters and more complex systems like the geometries for Mach-Zehnder and Michelson-type interferometers for atoms.

Micro-optical realization of arrays of selectively addressable dipole traps: a scalable configuration for quantum computation with atomic qubits.

We experimentally demonstrate novel structures for the realization of registers of atomic qubits: We trap neutral atoms in one- and two-dimensional arrays of far-detuned dipole traps obtained by focusing a red-detuned laser beam with a microfabricated array of microlenses. We are able to selectively address individual trap sites due to their large lateral separation of 125 microm. We initialize and read out different internal states for the individual sites. We also create two interleaved sets of trap arrays with adjustable separation, as required for many proposed implementations of quantum gate operations.

Incorporation of tritiated thymidine, leucine and histidine in murine tail epidermis after skin irritation (histoautoradiography).

Thymidine incorporation into epidermal DNA as well as leucine and histidine incorporation into epidermal protein were studied by histoautoradiography in female mice tail epidermis. Prior to in vitro incubation of skin samples with labelled precursors, tail skin was irritated mechanically by rubbing with fine sand paper, chemically by repeated topical administration of n-hexadecane and by feeding an essential fatty acid deficient diet. After these skin irritations, an increased thymidine labelling index and skin thickening were found. Leucine was shown to be incorporated into protein predominantly in basal epidermal cell layers, while histidine was incorporated predominantly in the granular layer. Especially after mechanical skin irritation, this difference was obvious.
