Thin-film superconducting resonator tunable to the ground-state hyperfine splitting of Rb
Z. Kim, C. P. Vlahacos, J. E. Hoffman +13
We describe a thin-film superconducting Nb microwave resonator, tunable to within 0.3 ppm of the hyperfine splitting of Rb at GHz. We coarsely tuned the re…

Electromechanical Wave Green's Function Estimation from Ambient Electrical Grid Frequency Noise
Scott Backhaus, Yilu Liu
Many electrical grid transients can be described by the propagation of electromechanical (EM) waves that couple oscillations of power flows over transmission lines and the inertia…
