Measuring Energy Differences by BEC Interferometry on a Chip
Florian Baumgartner, R. J. Sewell, S. Eriksson +4
We investigate the use of a Bose-Einstein condensate trapped on an atom chip for making interferometric measurements of small energy differences. We measure and explain the noise i…
Atom chip for BEC interferometry
R. J. Sewell, J. Dingjan, F. Baumgartner +8
We have fabricated and tested an atom chip that operates as a matter wave interferometer. In this communication we describe the fabrication of the chip by ion-beam milling of gold…
Atom detection and photon production in a scalable, open, optical microcavity
M. Trupke, J. Goldwin, B. Darquié +4
A microfabricated Fabry-Perot optical resonator has been used for atom detection and photon production with less than 1 atom on average in the cavity mode. Our cavity design combin…
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…
Microfabricated high-finesse optical cavity with open access and small volume
M. Trupke, E. A. Hinds, S. Eriksson +4
We present a novel microfabricated optical cavity, which combines a very small mode volume with high finesse. In contrast to other micro-resonators, such as microspheres, the struc…
Bose-Einstein Condensation on a Permanent-Magnet Atom Chip
C. D. J. Sinclair, E. A. Curtis, I. Llorente Garcia +5
We have produced a Bose-Einstein condensate on a permanent-magnet atom chip based on periodically magnetized videotape. We observe the expansion and dynamics of the condensate in o…
