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…
