Engineering excited-state interactions at ultracold temperatures
Michael Mills, Prateek Puri, Ming Li +5
Using a recently developed method for precisely controlling collision energy, we observe a dramatic suppression of inelastic collisions between an atom and ion (Ca + Yb) at low…
Blue-sky bifurcation of ion energies and the limits of neutral-gas sympathetic cooling of trapped ions
Steven J. Schowalter, Alexander J. Dunning, Kuang Chen +3
Sympathetic cooling of trapped ions through collisions with neutral buffer gases is critical to a variety of modern scientific fields, including fundamental chemistry, mass spectro…
Interferometric laser cooling of atomic rubidium
Alexander Dunning, Rachel Gregory, James Bateman +2
We report the 1-D cooling of Rb atoms using a velocity-dependent optical force based upon Ramsey matter-wave interferometry. Using stimulated Raman transitions between groun…
Composite pulses for interferometry in a thermal cold atom cloud
Alexander Dunning, Rachel Gregory, James Bateman +4
Atom interferometric sensors and quantum information processors must maintain coherence while the evolving quantum wavefunction is split, transformed and recombined, but suffer fro…
Actively stabilized wavelength-insensitive carrier elimination from an electro-optically modulated laser beam
Nathan Cooper, James Bateman, Alexander Dunning +1
We demonstrate a simple and robust technique for removal of the carrier wave from a phase-modulated laser beam, using a non-interferometric method that is insensitive to the modula…
The sensitivity of hyperfine structure to nuclear radius and quark mass variation
T. H. Dinh, A. Dunning, V. A. Dzuba +1
To search for the temporal variation of the fundamental constants one needs to know dependence of atomic transition frequencies on these constants. We study the dependence of the h…
