The performance of superconducting radio-frequency (SRF) cavities depends on the
condition of the niobium surface. Recently, various heat treatment methods have been …

We propose a theory of nonlinear surface resistance of a dirty superconductor in a strong
radio-frequency (rf) field, taking into account magnetic and nonmagnetic impurities, finite …

Surface structures on radio-frequency (RF) superconductors are crucially important in
determining their interaction with the RF field. Here we investigate the surface compositions …

Niobium is one of the most researched superconductors, both theoretically and
