Sub-Natural-Linewidth Quantum Interference Features Observed in Photoassociation of a Thermal Gas

October 7, 2005

Author(s)

R Dumke, J D. Weinstein, M Johanning, Kevin Jones, Paul D. Lett

By driving photoassociation transitions we form electronically excited molecules (Na$_2^*$) from ultra-cold (50-300 $\mu$K) Na atoms. Using a second laser to drive transitions from the excited state to a level in the molecular ground state, we are able to

Measurement and Modeling of Hyperfine- and Rotation-Induced State Mixing in Large Weakly Bound Sodium Dimers

May 1, 2005

Author(s)

Eite Tiesinga, Kevin Jones, Paul D. Lett, U Volz, Carl J. Williams, Paul S. Julienne

We present high-precision trap loss spectroscopy of excited Na_2 molecules obtained by the photoassociation of ultracold sodium atoms. Near the 3S+3P3/2 dissociation limit, hyperfine and rotational (Coriolis type) interactions cause significant mixing of

Abraham's Force on a Highly Dispersive Medium

February 2, 2004

Author(s)

Paul D. Lett, L Wang

We consider the radiation force on highly dispersive media. In doing so we reconsider an experiment proposed to measure the Abraham force term in the stress-energy tensor at optical frequencies by measuring the displacement of a transparent dielectric

Photoassociation Spectroscopy of the Lowest Triplet Potential of Na 2

February 1, 2004

Author(s)

R Dumke, M Johanning, J D. Weinstein, Paul D. Lett

We have performed a type of Autler-Townes spectroscopy to investigate the level structure of the triplet ground state potential of the sodium dimer. By driving photoassociation transitions with continuous-wave lasers, we state-selectively form excited

Realization of a Quantum Random Walk With Ultracold Atoms

February 1, 2004

Author(s)

D Ciampini, M B. d'Arcy, J M. Grossman, Kristian Helmerson, Paul D. Lett, William D. Phillips, A Vaziri, S L. Rolston

Classical random walks have many applications in computer science. Quantum random walks (QRWs) [1] have been suggested as the potential basis for quantum computing algorithms. Such algorithms have been reported, some of which offer an exponential speed-up
