Vortices and Quasiparticles in Superconducting Microwave Resonators
<p>Superconducting resonators with high quality factors are of great interest in many areas. However, the quality factor of the resonator can be weakened by many dissipation channels including trapped magnetic flux vortices and nonequilibrium quasiparticles which can significantly impact the …

Physics of Superconducting Travelling-Wave Parametric Amplifiers
Superconducting travelling-wave parametric amplifiers (TWPAs) are ultra-low-noise amplifiers that achieve amplification through the nonlinear kinetic inductance of superconductors. These devices can have near quantum-limited noise performance, and have important applications in quantum information …

Strong coupling between microwave photons and nanomagnet magnons
… coupling strength using lithographically defined superconducting resonators, we demonstrate high cooperativities between a resonator mode and a Kittel mode in nanometer thick Permalloy wires. Strong magnon-photon coupling is achieved with number of spins in the order of 1013, three orders of …

The physics of superconducting ring resonators
Superconducting microwave resonators with very high quality factor have been widely used in a large number of low-temperature experiments and applications over the past two decades. Numerous research on linear distributed, either half-wavelength or quarter-wavelength, and lumped element …
