Density dependence of the Ionization Avalanche in ultracold Rydberg gases
M. Siercke, F. E. Oon, A. Mohan +3
We report on the behaviour of the ionization avalanche in an ensemble of ultracold 87Rb atoms coupled to a high lying Rydberg state and investigate extensions to the current model…
Reconfigurable self-sufficient traps for ultracold atoms based on a superconducting square
M. Siercke, K. S. Chan, B. Zhang +3
We report on the trapping of ultracold atoms in the magnetic field formed entirely by persistent supercurrents induced in a thin film type-II superconducting square. The supercurre…
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…
Design of magnetic traps for neutral atoms with vortices in type-II superconducting micro-structures
B. Zhang, R. Fermani, T. Mueller +2
We design magnetic traps for atoms based on the average magnetic field of vortices induced in a type-II superconducting thin film. This magnetic field is the critical ingredient of…
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…
Heating rate and spin flip lifetime due to near field noise in layered superconducting atom chips
Rachele Fermani, Tobias Mueller, Bo Zhang +2
We theoretically investigate the heating rate and spin flip lifetimes due to near field noise for atoms trapped close to layered superconducting structures. In particular, we compa…
