Delayed four- and six-wave mixing in a coherently prepared atomic ensemble
D. Felinto, D. Moretti, R. A. de Oliveira +1
We report on the simultaneous observation, by delayed Bragg diffraction, of four- and six-wave mixing processes in a coherently prepared atomic ensemble consisting of cold cesium a…
Pulse pair generation from coherently prepared atomic ensembles
D. Moretti, D. Felinto, J. W. R. Tabosa
We report a detailed investigation on the generation of pulse pairs during the readout of a coherence grating stored in a cold atomic ensemble. The pulse shapes and the split of th…
Dynamics of a stored Zeeman coherence grating in an external magnetic field
D. Moretti, D. Felinto, J. W. R. Tabosa +1
We investigate the evolution of a Zeeman coherence grating induced in a cold atomic cesium sample in the presence of an external magnetic field. The gratings are created in a three…
Off-center coherent-state representation and an application to semiclassics
Fernando Parisio
By using the overcompleteness of coherent states we find an alternative form of the unit operator for which the ket and the bra appearing under the integration sign do not refer to…
