Measurement of differential polarizabilities at a mid-infrared wavelength in
C F A Baynham, E A Curtis, R M Godun +10
An atom exposed to an electric field will experience Stark shifts of its internal energy levels, proportional to their polarizabilities. In optical frequency metrology, the Stark s…
A low maintenance Sr optical lattice clock
Ian R. Hill, Richard Hobson, William Bowden +4
We describe the Sr optical lattice clock apparatus at NPL with particular emphasis on techniques used to increase reliability and minimise the human requirement in its operation. C…
Zeeman Slowers for Strontium based on Permanent Magnets
Ian R. Hill, Yuri B. Ovchinnikov, Elizabeth M. Bridge +2
We present the design, construction, and characterisation of longitudinal- and transverse-field Zeeman slowers, based on arrays of permanent magnets, for slowing thermal beams of a…
Shaking-induced dynamics of cold atoms in magnetic traps
I. Llorente García, B. Darquié, C. D. J. Sinclair +4
We describe an experiment in which cold rubidium atoms, confined in an elongated magnetic trap, are excited by transverse oscillation of the trap centre. The temperature after exci…
Experiments on a videotape atom chip: fragmentation and transport studies
I. Llorente Garcia, B. Darquie, E. A. Curtis +2
This paper reports on experiments with ultra-cold rubidium atoms confined in microscopic magnetic traps created using a piece of periodically-magnetized videotape mounted on an ato…
Pyramidal micro-mirrors for microsystems and atom chips
M. Trupke, F. Ramirez-Martinez, E. A. Curtis +8
Concave pyramids are created in the (100) surface of a silicon wafer by anisotropic etching in potassium hydroxide. High quality micro-mirrors are then formed by sputtering gold on…
