Adsorbate Electric Fields on a Cryogenic Atom Chip
K. S. Chan, M. Siercke, C. Hufnagel +1
We investigate the behaviour of electric fields originating from adsorbates deposited on a cryogenic atom chip as it is cooled from room temperature to cryogenic temperature. Using…
Magnetic confinement of neutral atoms based on patterned vortex distributions in superconducting disks and rings
B. Zhang, M. Siercke, K. S. Chan +3
We propose and analyze neutral atom traps generated by vortices imprinted by magnetic field pulse sequences in type-II superconducting disks and rings. We compute the supercurrent…
Programmable trap geometries with superconducting atom chips
T. Mueller, B. Zhang, R. Fermani +3
We employ the hysteretic behavior of a superconducting thin film in the remanent state to generate different traps and flexible magnetic potentials for ultra-cold atoms. The trap g…
Towards a guided atom interferometer based on a superconducting atom chip
T. Mueller, X. Wu, A. Mohan +3
We evaluate the realization of a novel geometry of a guided atom interferometer based on a high temperature superconducting microstructure. The interferometer type structure is obt…
All-optical generation and photoassociative probing of sodium Bose-Einstein condensates
R. Dumke, M. Johanning, E. Gomez +3
We demonsatrate an all optical technique to evaporatively produce sodium Bose-Einstein condensates (BEC). We use a crossed-dipole trap formed from light near 1060 nm, and a simple…
