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…

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…

Anomalous Josephson current through a ferromagnetic trilayer junction

Jun-Feng Liu, K. S. Chan

We studied the anomalous Josephson current appearing at zero phase difference in junctions coupled with a ferromagnetic trilayer which has noncoplanar magnetizations. A junct…

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…

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…

Resonant Tunneling through double-bended Graphene Nanoribbons

Z. Z. Zhang, Kai Chang, K. S. Chan

We investigate theoretically resonant tunneling through double-bended graphene nanoribbon structures, i.e., armchair-edged graphene nanoribbons (AGNRs) in between two semi-infinite…
