We present a phenomenological description of the high-frequency vortex dynamics in and
discuss the main parameters related to vortex motion, namely the viscous drag coefficient …

Most of superconductors in a magnetic field are penetrated by a lattice of quantized flux
vortices. In the presence of a transport current causing the vortices to cross sample edges …

In the present study the radio-frequency complex response of trapped vortices in
superconductors is calculated and compared to experimental data previously published …

We give the exact solution to the problem of a random walk on the Bethe lattice through a
mapping on an asymmetric random walk on the half-line. We also study the continuous limit …

The available experimental data on non-linear microwave effects in superconductors and
some theoretical explanations of these, published since 1964, are reviewed. Various …

The field‐dependent nonresonant absorption at microwave (9.1 GHz) and radio (19.5 MHz)
frequencies has been studied in the superconducting state of YBa2Cu3O7− x pellets and …

We have measured the magnetic-field and temperature dependence of the surface
resistance R s of grain-aligned YBa 2 Cu 3 O x. Experiments were conducted on ab-plane …

This paper discusses some of the major experimental features of microwave nonlinearity in
high temperature superconductors, both intrinsic and extrinsic. The case is made for solving …

Superconducting niobium accelerating cavities are devices operating in radiofrequency and
able to accelerate charged particles up to energy of tera-electron-volts. Such accelerating …

We present a phenomenological model for the frequency-dependent fluxon complex
resistivity in which the fluxon viscosity η is a central parameter. We use the high-frequency …
