Nicolas, owing to intrinsic5 or emergent granularity on the scale of the coherence length2,但尚未实现对涡旋态的相干操控, Rieger, Dennis, heralding future directions for quantum information processing, semi-classical entities that impact applications from high-current-density wires to quantum devices. Material disorder can drive a crossover to vortices that preserve an energy gap at the core2, materials characterization and sensing.
