Polarization-based Light-Atom Quantum Interface with an All-optical Trap
Marcin Kubasik, Marco Koschorreck, Mario Napolitano +5
We describe the implementation of a system for studying light-matter interactions using an ensemble of cold rubidium 87 atoms, trapped in a single-beam optical dipole trap.…
Intensity-dependent dispersion under conditions of electromagnetically induced transparency in coherently prepared multi-state atoms
Andrew D. Greentree, Derek Richards, J. A. Vaccaro +4
Interest in lossless nonlinearities has focussed on the the dispersive properties of systems under conditions of electromagnetically induced transparency (EIT). We generalize t…
Resonant and off-resonant transients in electromagnetically induced transparency: turn-on and turn-off dynamics
Andrew D. Greentree, T. B. Smith, S. R. de Echaniz +4
This paper presents a wide-ranging theoretical and experimental study of non-adiabatic transient phenomena in a EIT system when a strong coupling field is rapidly switched on o…
Observation of transient gain without population inversion in a laser-cooled rubidium lambda system
S. R. de Echaniz, Andrew D. Greentree, A. V. Durrant +3
We have observed clear Rabi oscillations of a weak probe in a strongly driven three-level lambda system in laser-cooled rubidium for the first time. When the coupling field is non-…
Observations of a doubly driven V system probed to a fourth level in laser-cooled rubidium
S. R. de Echaniz, Andrew D. Greentree, A. V. Durrant +3
Observations of a doubly driven V system probed to a fourth level in an N configuration are reported. A dressed state analysis is also presented. The expected three-peak spectrum i…
Prospects for photon blockade in four level systems in the N configuration with more than one atom
Andrew D. Greentree, John A. Vaccaro, Sebastian R. de Echaniz +2
We show that for appropriate choices of parameters it is possible to achieve photon blockade in idealised one, two and three atom systems. We also include realistic parameter range…
