Oval-shaped resonance distortion as a signature of quasiparticle heating effect in a niobium superconducting resonator
Zhenyuan Sun, Genting Dai, Xiao Geng +8
We investigate the nonlinear behavior of a superconducting microwave resonator subjected to a dissipative mechanism where the associated quality factor (Q factor) decreases with in…
