摘要：
We experimentally study giant vortex states (GVSs) and multivortex states (MVSs) in a mesoscopic superconducting square under local supercurrent injection. By using the multiple-small-tunnel-junction measurement, we find that the magnetic field for the transition between a GVS and an MVS with a fixed vorticity depends on the magnitude of the injected supercurrent. This result indicates the possibility of manipulating quantum vortex states with supercurrent injection.
