Topological effects on magnitude of persistent current in a ring
P. Singha Deo
We show that defects in 1D rings decrease the conductance (when the ring is opened up) many more times than it decreases the persistent currents. This means that the states in such…

How general is Legett's conjecture for a mesoscopic ring?
P. Singha Deo
It has been shown[19] that in a loop of length u to which a single stub of length v is attached (fig. 1 in ref. 19), the parity effect is completely destroyed when v/u. It was…
