Dynamic high-resolution optical trapping of ultracold atoms

Dynamic high-resolution optical trapping of ultracold atoms

Gauthier Guillaume et al, 2020

Advances In Atomic, Molecular, and Optical Physics Volume 70, 2021, Pages 1-101

Our review of configured optical trapping techniques for cold atoms has been posted on the arXiv. We have aimed for a detailed technical review that highlights some of the subtleties in implementing acousto-optic deflector, DMD and SLM traps, as a complete guide to the experimentalist. The chapter will appear in Advances in Atomic Molecular and Optical Physics later this year.

Engineering Spin Domains in a Binary BEC

Engineering Spin Domains in a Binary BEC

A Pritchard et. al

In a 2-component BEC, confined in an all optical line trap, we use a spin-dependent optical barrier beam to localise one of the spin components. By time-averaging the beam we can furthermore create multiple spin sites.

Quantitative Acoustic Models for Superfluid Circuits

Gauthier Guillaume et al, 2019
Physical Review Letters, 123, 26

We experimentally realize a highly tunable superfluid oscillator circuit in a quantum gas of ultracold atoms and develop and verify a simple lumped-element description of this circuit.

Giant vortex clusters in a two-dimensional quantum fluid

Giant vortex clusters in a two-dimensional quantum fluid

Gauthier Guillaume et al, 2019
Science, 364, 6447, pp. 1264-1267

Adding energy to a system through transient stirring usually leads to more disorder. In contrast, point-like vortices in a bounded two-dimensional fluid are predicted to reorder above a certain energy, forming persistent vortex clusters.

Phase and micromotion of Bose-Einstein condensates in a time-averaged ring trap

Bell Thomas A. et al, 2018
Physical Review A, 98, 1

Rapidly scanning magnetic and optical dipole traps have been widely utilized to form time-averaged potentials for ultracold quantum gas experiments.

Bose–Einstein condensation in large time-averaged optical ring potentials

Bose–Einstein condensation in large time-averaged optical ring potentials

Bell T A et al, 2016
New Journal of Physics

Interferometric measurements with matter waves are established techniques for sensitive gravimetry, rotation sensing, and measurement of surface interactions, but compact interferometers will require techniques based on trapped geometries.

Note: High turn density magnetic coils with improved low pressure water cooling for use in atom optics

McKay Parry Nicholas et al, 2014
Review of Scientific Instruments, 85, 8, pp. 86103

We describe a magnetic coil design utilizing concentrically wound electro-magnetic insulating (EMI) foil (25.4 μm Kapton backing and 127 μm thick layers). The magnetic coils are easily configurable for differentcoil sizes, while providing large surfaces for low-pressure (0.12 bar) water cooling.
