摘要: We employ the hysteretic behavior of a superconducting thin film in remanent state to generate different traps and flexible magnetic potentials for ultracold atoms. The trap geometry can be programed by externally applied fields. This approach atom optics is demonstrated three types realized on single microstructure: Z-type trap, double bias-field-free trap. Our studies show that superconductors provide versatile platform applications quantum gases.
