Hyperfine Spectroscopy of Optically Trapped Atoms
A. Kaplan, M. F. Andersen, T. Grünzweig +1
We perform spectroscopy on the hyperfine splitting of Rb atoms trapped in far-off-resonance optical traps. The existence of a spatially dependent shift in the energy levels…
Decay of Quantum Correlations in Atom Optics Billiards with Chaotic and Mixed Dynamics
M. F. Andersen, A. Kaplan, T. Grünzweig +1
We perform echo spectroscopy on ultra cold atoms in atom optics billiards, to study their quantum dynamics. The detuning of the trapping laser is used to change the ``perturbation'…
Echo spectroscopy and Atom Optics Billiards
M. F. Andersen, A. Kaplan, T. Grünzweig +1
We discuss a recently demonstrated type of microwave spectroscopy of trapped ultra-cold atoms known as "echo spectroscopy" [M.F. Andersen et. al., Phys. Rev. Lett., in press (2002)…
Echo spectroscopy and quantum stability of trapped atoms
M. F. Andersen, A. Kaplan, N. Davidson
We investigate the dephasing of ultra cold ^{85}Rb atoms trapped in an optical dipole trap and prepared in a coherent superposition of their two hyperfine ground states by interact…
Suppression of inhomogeneous broadening in rf spectroscopy of optically trapped atoms
Ariel Kaplan, Mikkel Fredslund Andersen, Nir Davidson
We present a novel method for reducing the inhomogeneous frequency broadening in the hyperfine splitting of the ground state of optically trapped atoms. This reduction is achieved…
