Nonlinear magneto-optical resonances occurring for near-zero magnetic field are studied in
Rb vapor using light-noise spectroscopy. With a balanced detection polarimeter, we observe …

We have experimentally observed switching between photon-photon correlations and
anticorrelations between two orthogonally polarized laser beams in an electromagnetically …

Using electromagnetically induced transparency (EIT), it is possible to delay and store light
in atomic ensembles. Theoretical modeling and recent experiments have suggested that the …

We have studied relative-intensity fluctuations for a variable set of orthogonal elliptic
polarization components of a linearly polarized laser beam traversing a resonant 87 Rb …

We show that three-level atoms excited by two cavity modes in a Λ configuration close to
electromagnetically induced transparency can produce strongly squeezed bright beams or …

We present a quantum mechanical treatment for both atomic and field fluctuations of an
atomic ensemble interacting with propagating fields, either in electromagnetically induced …

We show that strong squeezing and entanglement can be generated at the output of a cavity
containing atoms interacting with two fields in a coherent population trap** situation, on …

We demonstrate and characterize two coherent phenomena that can mitigate the effects of
laser phase noise for electromagnetically induced transparency (EIT): a laser-power …

Quantum entanglement provides an essential resource for quantum computation, quantum
communication and quantum network. How to conveniently and efficiently produce …

High degrees of intensity correlation between two independent lasers were observed after
propagation through a rubidium vapor cell in which they generate Electromagnetically …
