Light storage via coherent population oscillation in a thermal cesium vapor
A. J. F. de Almeida, J. Sales, M. -A. Maynard +5
We report on the storage of light via the phenomenon of Coherent Population Oscillation (CPO) in an atomic cesium vapor at room temperature. In the experiment the optical informati…
Off-axis retrieval of orbital angular momentum of light stored in cold atoms
R. A. de Oliveira, L. Pruvost, P. S. Barbosa +5
We report on the storage of orbital angu- lar momentum (OAM) of light of a Laguerre-Gaussian mode in an ensemble of cold cesium atoms and its re- trieval along an axis different fr…
Single-Photon Superradiance in Cold Atoms
Rafael A. de Oliveira, Milrian S. Mendes, Weliton S. Martins +3
The interaction of an ensemble of atoms with common vacuum modes may lead to an enhanced emission into these modes. This phenomenon, known as superradiance, highlights the coherent…
Coherent-State Overcompleteness, Path Integrals, and Weak Values
Fernando Parisio
In the Hilbert space of a quantum particle the standard coherent-state resolution of unity is written in terms of a phase-space integration of the outer product $|z\rangle \langle…
