Three-Axis Measurement and Cancellation of Background Magnetic Fields to less than 50 uG in a Cold Atom Experiment
Aaron Smith, Brian E. Anderson, Souma Chaudhury +1
Many experiments involving cold and ultracold atomic gases require very precise control of magnetic fields that couple to and drive the atomic spins. Examples include quantum contr…
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…
