Dynamical Conductivity across the Disorder-Tuned Superconductor-Insulator Transition
We calculate the dynamical conductivity σ(ω) and the bosonic (pair) spectral function P(ω) from quantum Monte Carlo simulations across clean and disorder-driven superconductor-insulator transitions (SITs). We identify characteristic energy scales in the superconducting and insulating phases that van...
