Abstract :
The paper reports on the first observation of nonlinear Faraday rotation (NFR) with cold atoms prepared in a magneto- optical trap (MOT) at ~100 muK temperature. The nonlinearity of rotation results from long-lived coherence of ground-state Zeeman sublevels, which makes NFR a candidate for the study and sensitive detection of qubits.
