Abstract:We explore a novel mechanism for control of periodicity in persistent current in a twisted normal metal loop threaded by a magnetic flux &phi. A simple tight-binding model is used to describe the system. Quite interestingly we see that, depending on the number of twist p, the persistent current exhibits &phi0/p (&phi0 = ch/e, the elementary flux-quantum) periodicity. Such fractional periodicity provides a new finding in the study of persistent current.
