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…
Trapping of ultra-cold atoms with the magnetic field of vortices in a thin film superconducting micro-structure
T. Müller, B. Zhang, R. Fermani +5
We store and control ultra-cold atoms in a new type of trap using magnetic fields of vortices in a high temperature superconducting micro-structure. This is the first time ultra-co…
Direct Observation of Second Order Atom Tunnelling
S. Foelling, S. Trotzky, P. Cheinet +5
Tunnelling of material particles through a classically impenetrable barrier constitutes one of the hallmark effects of quantum physics. When interactions between the particles comp…
