Tuning microwave losses in superconducting resonators
Alex Gurevich
Performance of superconducting resonators, particularly cavities for particle accelerators and micro cavities and thin film resonators for quantum computations and photon detectors…
On the effect of localized and delocalized quasiparticles on a nonlinear conductivity of superconductors
A. Gurevich
Recently Deyo et al. [\prb {\bf 106}, 104502 (2022)] suggested that the surface resistance of a superconductor under strong electromagnetic field can be affected by fiel…
Challenges and opportunities of srf theory for next generation particle accelerators
Alex Gurevich, Takayuki Kubo, James A. Sauls
We suggest a program to establish theoretical performance limits of srf cavities using modern theories of nonequilibrium superconductivity under a strong electromagnetic field. The…
Nonlinear Meissner effect in Nb3Sn coplanar resonators
J. Makita, C. Sundahl, G. Ciovati +2
We investigated the nonlinear Meissner effect (NLME) in NbSn thin film coplanar resonators by measuring the resonance frequency as a function of a parallel magnetic field at di…
Effect of random pinning on nonlinear dynamics and dissipation of a vortex driven by a strong microwave current
W. P. M. R. Pathirana, A. Gurevich
We report numerical simulations of a trapped elastic vortex driven by a strong ac magnetic field parallel to the surface of a superconducting film. The surface resis…
Dynamic pair-breaking current, critical superfluid velocity and nonlinear electromagnetic response of nonequilibrium superconductors
Ahmad Sheikhzada, Alex Gurevich
We report numerical calculations of a dynamic pairbreaking current density and a critical superfluid velocity in a nonequilibrium superconductor carrying a uniform, lar…
