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…
Excitation of Collective Modes in a Chiral Superfluid by Thermal Quench
Noble Gluscevich, J. A. Sauls
Based on time-dependent Ginzburg-Landau field theory we show that rapid cooling through the second-order phase transition into superfluid He-A excites collective modes of newly…
Generation of Quantum Turbulence by Neutrino Cooling in Neutron Stars
J. A. Sauls
The interior crust and much of the liquid core of neutron stars is believed to be a quantum liquid mixture of neutron and proton superfluids and a relativistic electron liquid. Qua…
Trapping and Tunneling of Hydrogen, Deuterium and Oxygen in Niobium
Abdulaziz Abogoda, J. A. Sauls
We investigate isolated O-H and O-D pairs trapped in BCC Nb using a machine-learning interatomic potential (MLIP) trained to density-functional theory (DFT). The MLIP enables large…
Kibble-Zurek Dynamics & Statistics of Topological Defects in Chiral Superfluid He Films
Noble Gluscevich, J. A. Sauls
In equilibrium, confined films of superfluid He-A have the chiral axis, , locked normal to the surface of the film. There are two degenerate ground states $\hat{\el…
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…
