Microwave Response of Superconductors with Paramagnetic Impurities
Mehdi Zarea, J. A. Sauls
We develop theoretical methods to predict the effects of paramagnetic impurities on the microwave response of conventional spin-singlet superconductors. Our focus is on superconduc…
Electromagnetic Response of Disordered Superconducting Cavities
Mehdi Zarea, Hikaru Ueki, J. A. Sauls
We present results for the resonant frequency shift and quality factor of disordered Nb SRF cavities driven out of equilibrium by the resonant microwave field. The theory is based…
Electromagnetic Response of Superconducting RF Cavities
Hikaru Ueki, Mehdi Zarea, J. A. Sauls
Recently reported anomalies in frequency shift of order $δf\sim 0.1 -10\,\mbox{kHz}$ for Niobium SRF cavities in a narrow temperature region near $T_c\simeq 9\,\mbox{K}$ are sensit…
Niobium in clean limit: an intrinsic type-I superconductor
Ruslan Prozorov, Mehdi Zarea, James A. Sauls
Niobium is one of the most researched superconductors, both theoretically and experimentally. It is enormously significant in all branches of superconducting applications, from pow…
Anisotropic superconductivity of niobium based on its response to non-magnetic disorder
Makariy A. Tanatar, Daniele Torsello, Kamal R. Joshi +8
Niobium is one of the most studied superconductors, both theoretically and experimentally. It is tremendously important for applications, and it has the highest superconducting tra…
The Frequency Shift and Q of Disordered Superconducting RF Cavities
Hikaru Ueki, Mehdi Zarea, J. A. Sauls
Niobium superconducting radio-frequency (SRF) cavities for high energy accelerator applications have been greatly improved in terms of the quality factor by techniques such as…
