Complete Characterization of Static and Dynamic Electromagnetic Response near 2D Percolative Superconductor-Insulator Transitions

We present a comprehensive description of the superfluid stiffness, diamagnetic susceptibility, electric susceptibility, and dynamical conductivity of random inductor-capacitor networks on square lattices. The results are relevant to superconductor-insulator transitions in coarse-grained superconductor-insulator composites dominated by percolation physics. Results were obtained using Chebyshev equation-of-motion and bond-propagation algorithms customized for our models, and found to be in mutual agreement.
