摘要: We investigate superconducting chip structures for trapping and manipulating atoms. These are based on the average magnetic field of vortices induced in a type-II thin film. This is critical ingredient demonstrated vortex-based atom trap, which operate without transport current. employ hysteretic behavior film remanent state to generate different traps flexible potentials ultra-cold The experimental realization can be described by Bean's critical-state method model vortex through mesoscopic super currents strip. Various patterns obtained programming loading-field current sequences. Furthermore we will discuss expected enhanced lifetime atoms trapped close surface comparison with metallic surface.
