Quantum Control of the Hyperfine Spin of a Cs Atom Ensemble
Souma Chaudhury, Seth Merkel, Tobias Herr +3
We demonstrate quantum control of a large spin-angular momentum associated with the F=3 hyperfine ground state of 133Cs. A combination of time dependent magnetic fields and a stati…
A Continuous Non-demolition Measurement of the Cs Clock Transition Pseudo-spin
Souma Chaudhury, Greg A. Smith, Kevin Schulz +1
We demonstrate a weak continuous measurement of the pseudo-spin associated with the clock transition in a sample of Cs atoms. Our scheme uses an optical probe tuned near the D1 tra…
Continuous Weak Measurement and Nonlinear Dynamics in a Cold Spin Ensemble
Greg A. Smith, Souma Chaudhury, Andrew Silberfarb +2
A weak continuous quantum measurement of an atomic spin ensemble can be implemented via Faraday rotation of an off-resonance probe beam, and may be used to create and probe nonclas…
Faraday spectroscopy in an optical lattice: a continuous probe of atom dynamics
Greg Smith, Souma Chaudhury, Poul S. Jessen
The linear Faraday effect is used to implement a continuous measurement of the spin of a sample of laser cooled atoms trapped in an optical lattice. One of the optical lattice beam…
