Manipulating and measuring single atoms in the Maltese cross geometry
Lorena C. Bianchet, Natalia Alves, Laura Zarraoa +2
We describe optical methods for trapping, cooling, and observing single Rb atoms in a four-lens "Maltese cross" geometry (MCG). The use of four high numerical-aperture lense…

Maltese cross coupling to individual cold atoms in free space
Natalia Bruno, Lorena C. Bianchet, Nan Li +3
We report on the simultaneous observation from four directions of the fluorescence of single Rb atoms trapped at the common focus of four high numerical aperture (${\rm NA}=…

Fock-state superradiance in a cold atomic ensemble
D. F. Barros, L. F. Muñoz-Martínez, L. Ortiz-Gutiérrez +7
A simplified theory for the wavepackets of the photons emitted during the read process of a quantum memory formed by cold atoms is provided. We arrive at analytical expressions for…
