  1. Quantum oscillations in a superconducting bismuth nanowire Thomas E. Mallouk, Pennsylvania State Univ University Park, DMR 0820404 Mingliang Tian, Jian Wang, Qi Zhang, Nitesh Kumar, T. E. Mallouk, M. H. W. Chan, Center for Nanoscale Science, Penn State University - DMR 0820404 In contrast to bulk bismuth, crystalline bismuth nanowires are superconducting below 1.3 K. The residual resistance of a 72 nm wire at low temperature displays oscillations periodic in the parallel magnetic field H, with a period correspond to the superconducting flux quantum (left). This Little-Parks-like effect suggests that superconductivity originates in a surface shell on the wire. When H is perpendicular to the wire axis, the resistance shows oscillations with a 1/H periodicity typical of fermionic systems (right), indicating a novel coexistence of fermionic and bosonic states.
