Direct observation of quantum superconducting fluctuations in an insulating groundstate
N. P. Armitage, R. Crane, G. Sambandamurthy +3
We review our recent measurements of the complex AC conductivity of thin InO_x films studied as a function of magnetic field through the nominal 2D superconductor-insulator transit…
Fluctuations, dissipation, and nonuniversal superfluid jumps in two-dimensional superconductors
R. W. Crane, N. P. Armitage, A. Johansson +3
We report a comprehensive study of the complex AC conductivity of thin effectively 2D amorphous superconducting InO_x films at zero applied field. Below a temperature scale T_c0 wh…
Survival of superconducting correlations across the 2D superconductor-insulator transition: A finite frequency study
R. W. Crane, N. P. Armitage, A. Johansson +3
The complex ac conductivity of thin highly disordered InOx films was studied as a function of magnetic field through the nominal two-dimensional superconductor-insulator transition…
Angular dependence of the magnetic-field driven superconductor-insulator transition in thin films of amorphous indium-oxide
A. Johansson, N. Stander, E. Peled +2
A significant anisotropy of the magnetic-field driven superconductor-insulator transition is observed in thin films of amorphous indium-oxide. The anisotropy is largest for more di…
Nanowire Acting as a Superconducting Quantum Interference Device
A. Johansson, G. Sambandamurthy, N. Jacobson +2
We present the results from an experimental study of the magneto-transport of superconducting wires of amorphous Indium-Oxide, having widths in the range 40 - 120 nm. We find that,…
Power law resistivity behavior in 2D superconductors across the magnetic-field tuned superconductor-insulator transition
G. Sambandamurthy, A. Johansson, E. Peled +3
We present the results of a systematic study of thin-films of amorphous indium-oxide near the superconductor-insulator transition. We show that the film's resistivity follows a sim…
