We have theoretically studied the time averaged adiabatic potential (TAAP) scheme for realizing different atom trapping geometries such as double-well, ring, asymmetric ring. The versatility of TAAP has been shown control and manipulation these via variation in orbiting (TOP) fields radio frequency (rf) fields. conversion from one geometry to another is also possible.

The effect of imprinting symmetric and displaced vortex structures into an antiferromagnetic material is investigated in micron-sized disks consisting of exchange coupled ferromagnetic-antiferromagnetic bilayers. The imprint of displaced vortices manifests itself by the occurrence of a new type of asymmetric hysteresis loops characterized by curved, reversible, central sections with nonzero rem...

o bjectives: headgears are among the effective orthodontic appliances to achieve treatment goals. unilateral molar distal movement is sometimes needed during an orthodontic treat- ment, which can be achieved by an asymmetric headgear. different unilateral headgears have been introduced. the main goal of this study was to analyze the force system of uni- lateral expanded outer bow asymmetric hea...
