A large-momentum-transfer Raman atom interferometer without -reversal
Guanchen Peng, Bryony Lanigan, R. Shah +5
We present a Raman atom interferometer using large momentum transfer without reversing the direction of the effective wavevector (-reversal). More specifically, we use a microwa…
Enhanced oscillation lifetime of a Bose-Einstein condensate in the 3D/1D crossover
B. Yuen, I. Barr, J. P. Cotter +2
We have measured the damped motion of a trapped Bose-Einstein condensate, oscillating with respect to a thermal cloud. The cigar-shaped trapping potential provides enough transvers…
A surface-patterned chip as a strong source of ultra-cold atoms for quantum technologies
C. C. Nshii, M. Vangeleyn, J. P. Cotter +7
Laser cooled atoms are central to modern precision measurements. They are also increasingly important as an enabling technology for experimental cavity quantum electrodynamics, qua…
Characteristics of integrated magneto-optical traps for atom chips
S Pollock, J P Cotter, A Laliotis +2
We investigate the operation of pyramidal magneto-optical traps (MOTs) microfabricated in silicon. Measurements of the loading and loss rates give insight into the role of the near…
An EIT search for Lorentz violating signals
J. P. Cotter, B. Varcoe
A test of Lorentz invariance has been performed using an EIT resonance as a precision frequency discriminator within an Ives-Stilwell like apparatus. We analyse the experiment with…
