Production of ultracold Cs*Yb molecules by photoassociation
Alexander Guttridge, Stephen A. Hopkins, Matthew D. Frye +3
We report the production of ultracold heteronuclear CsYb molecules through one-photon photoassociation applied to an ultracold atomic mixture of Cs and Yb confined in an optica…
Interspecies thermalization in an ultracold mixture of Cs and Yb in an optical trap
A. Guttridge, S. A. Hopkins, S. L. Kemp +3
We present measurements of interspecies thermalization between ultracold samples of Cs and either Yb or Yb. The two species are trapped in a far-off-resonan…
A versatile dual-species Zeeman slower for caesium and ytterbium
S. A. Hopkins, K. Butler, R. Freytag +5
We describe the design, construction and operation of a versatile dual-species Zeeman slower for both Cs and Yb, which is easily adaptable for use with other alkali metals and alka…
Direct loading of a large Yb MOT on the transition
A Guttridge, S A Hopkins, S L Kemp +6
We report a robust technique for laser frequency stabilisation that enables the reproducible loading of in excess of 10 Yb atoms from a Zeeman slower directly into a magneto-…
Production and characterization of a dual species magneto-optical trap of cesium and ytterbium
S. L. Kemp, K. L. Butler, R. Freytag +4
We describe an apparatus designed to trap and cool a Yb and Cs mixture. The apparatus consists of a dual species effusive oven source, dual species Zeeman slower, magneto-optical t…

A L Marchant, S Haendel, T P Wiles +2
We report on the guided transport of an atomic sample along an optical waveguide up to a room-temperature dielectric surface. The technique exploits a simple hybrid trap consisting…

We report an apparatus and method capable of producing Bose-Einstein condensates (BECs) of ~1x10^6 87Rb atoms, and ultimately designed for sympathetic cooling of 133Cs and the crea…
Magnetic merging of ultracold atomic gases of Rb and Rb
S Händel, T P Wiles, A L Marchant +3
We report on the magnetic merging of ultracold atomic gases of Rb and Rb by the controlled overlap of two initially spatially-separated magnetic traps. We present a d…
Off resonance laser frequency stabilization using the Faraday effect
A. L. Marchant, S. Haendel, T. P. Wiles +3
We present a simple technique for stabilization of a laser frequency off resonance using the Faraday effect in a heated vapor cell with an applied magnetic field. In particular we…
The Experimental Observation of a Superfluid Gyroscope in a dilute Bose Condensed Gas
E. Hodby, S. A. Hopkins, G. Hechenblaikner +2
We have observed a superfluid gyroscope effect in a dilute gas Bose-Einstein condensate. A condensate with a vortex possesses a single quantum of angular momentum and this causes t…
The Moment of Inertia and the Scissors Mode of a Bose-condensed Gas

We relate the frequency of the scissors mode to the moment of inertia of a trapped Bose gas at finite temperature in a semi-classical approximation. We apply these theoretical resu…
