Quantum Phase Transitions and Continuous Observation of Spinor Dynamics in an Antiferromagnetic Condensate
Yingmei Liu, Sebastian Jung, Stephen E. Maxwell +3
Condensates of spin-1 sodium display rich spin dynamics due to the antiferromagnetic nature of the interactions in this system. We use Faraday rotation spectroscopy to make a conti…
Squeezed Light and Entangled Images from Four-Wave-Mixing in Hot Rubidium Vapor
Raphael C Pooser, Vincent Boyer, Alberto M. Marino +1
Entangled multi-spatial-mode fields have interesting applications in quantum information, such as parallel quantum information protocols, quantum computing, and quantum imaging. We…
Violation of the Cauchy-Schwarz Inequality in the Macroscopic Regime
A. M. Marino, V. Boyer, P. D. Lett
We have observed a violation of the Cauchy-Schwarz inequality in the macroscopic regime by more than 8 standard deviations. The violation has been obtained while filtering out only…
Generation of spatially broadband twin beams for quantum imaging
V. Boyer, A. M. Marino, P. D. Lett
We generate spatially multimode twin beams using 4-wave mixing in a hot atomic vapor in a phase-insensitive traveling-wave amplifier configuration. The far-field coherence area mea…
Spinor Dynamics in an Antiferromagnetic Spin-1 Condensate
A. T. Black, E. Gomez, L. D. Turner +2
We observe coherent spin oscillations in an antiferromagnetic spin-1 Bose-Einstein condensate of sodium. The variation of the spin oscillations with magnetic field shows a clear si…
Ultraslow propagation of matched pulses by four-wave mixing in an atomic vapor
V. Boyer, C. F. McCormick, E. Arimondo +1
We have observed the ultraslow propagation of matched pulses in nondegenerate four-wave mixing in a hot atomic vapor. Probe pulses as short as 70 ns can be delayed by a tunable tim…
