Dynamical tunnelling with ultracold atoms in magnetic microtraps
Martin Lenz, Sebastian Wüster, Christopher J. Vale +5
The study of dynamical tunnelling in a periodically driven anharmonic potential probes the quantum-classical transition via the experimental control of the effective Planck's const…
Calibration of a single atom detector for atomic micro chips
A. Stibor, S. Kraft, T. Campey +6
We experimentally investigate a scheme for detecting single atoms magnetically trapped on an atom chip. The detector is based on the photoionization of atoms and the subsequent det…
Atom counting in ultra-cold gases using photoionisation and ion detection
T. Campey, C. J. Vale, M. J. Davis +5
We analyse photoionisation and ion detection as a means of accurately counting ultra-cold atoms. We show that it is possible to count clouds containing many thousands of atoms with…
Combined chips for atom-optics
A. Guenther, M. Kemmler, S. Kraft +3
We present experiments with Bose-Einstein condensates on a combined atom chip. The combined structure consists of a large-scale "carrier chip" and smaller "atom-optics chips", cont…
Foil-based atom chip for Bose-Einstein condensates
C. J. Vale, B. Upcroft, M. J. Davis +2
We describe a novel method of fabricating atom chips that are well suited to the production and manipulation of atomic Bose-Einstein condensates. Our chip was created using a silve…
Laser frequency locking by direct measurement of detuning
A. Ratnapala, C. J. Vale, A. G. White +3
We present a new method of laser frequency locking in which the feedback signal is directly proportional to the detuning from an atomic transition, even at detunings many times the…
