Abstract
We have calculated the persistent currents and the density of states in an open metallic ring connected to an electron reservoir in the presence of a magnetic flux. As a special case, we have considered the situation wherein electrons enter and leave the ring in a sub-barrier regime characterised by evanescent modes throughout the circumference of the ring. In such a situation, the persistent current arises due to two non-classical effects, namely, Aharonov-Bohm effect and quantum tunnelling.
