Injection-locking of violet laser diodes with a 3.2GHz offset frequency for driving Raman transitions in 43Ca+
B. C. Keitch, N. R. Thomas, D. M. Lucas
Two cw single-mode violet (397nm) diode lasers are locked to a single external-cavity master diode laser by optical injection locking. A double-pass 1.6GHz acousto-optic modulator…
Long-lived mesoscopic entanglement outside the Lamb-Dicke regime
M. J. McDonnell, J. P. Home, D. M. Lucas +7
We create entangled states of the spin and motion of a single Ca ion in a linear ion trap. The motional part consists of coherent states of large separation and long coh…
Imaging of s and d partial-wave interference in quantum scattering of identical bosonic atoms
Nicholas R. Thomas, Niels Kjaergaard, Paul S. Julienne +1
We report on the direct imaging of s and d partial-wave interference in cold collisions of atoms. Two ultracold clouds of Rb87 atoms were accelerated by magnetic fields to collide…
Bragg spectroscopy with an accelerating Bose-Einstein condensate
R. Geursen, N. R. Thomas, A. C. Wilson
We present the results of Bragg spectroscopy performed on an accelerating Bose-Einstein condensate. The Bose condensate undergoes circular micro-motion in a magnetic TOP trap and t…
Double-well magnetic trap for Bose-Einstein condensates
N. R. Thomas, C. J. Foot, A. C. Wilson
We present a magnetic trapping scheme for neutral atoms based on a hybrid of Ioffe-Pritchard and Time-averaged Orbiting Potential traps. The resulting double-well magnetic potentia…
RF coupling of a Bose-Einstein condensate in a TOP trap
J. L. Martin, C. R. McKenzie, N. R. Thomas +2
A radio frequency (RF) transition is used to convert a pure F=2,mF=2 87Rb Bose-Einstein condensate confined in a TOP trap to a mixture of F=2,mF=2 and F=2,mF=1 states. We show that…
