摘要：

Semiclassical theory relates mesoscopic persistent currents to classical periodic orbits. This is used to demonstrate that persistent currents are a sensitive probe of quantum chaos, exhibiting different universal dependences on the Fermi velocity for integrable and for completely chaotic ballistic microstructures. A study of the Sinai-billiard geometry reveals that the universality classes do not coincide with those of the spectral spacing distribution. Our conclusions are supported by numerical calculations.
