摘要
We theoretically investigate the transmission probability and the persistent current in an open quantum ring threaded by the magnetic flux. From the numerical results, we find that the two observable quantities both show a periodic characteristic with the increase of the magnetic flux, and they strongly depend on the dimensionless wave vector and the central angle as well as the magnetic flux.
