Cavity perturbation experiments to measure the complex surface impedance (surface resistance and surface reactance) of novel superconductors. Papers by Seokjin Bae and by Arthur Carlton-Jones of the Anlage Lab.
The Cooper pair instability paper
(Phys. Rev. 104, 1189 (1956))
Strategy for enhancing superconducting Tc: Increase the density of states D(EFermi) with a van Hove singularity or a flat band at the Fermi energy (e.g. twisted bilayer graphene)
BCS theory assumes equal abundance of spin-up and spin-down electrons. An interesting AMO paper shows that Fermionic superfluidity is robust against a
substantial imbalance in spin populations.
Lecture 9 The BCS Variational Calculation and the Self-Consistent Gap Equation
Calculation of BCS Surface Resistance and Penetration Depth (SRIMP)
Semiclassical model of superconducting penetration depth in anisotropic superconductors (ignores scattering) by Chandrasekhar and Einzel. The key equations have been re-expressed by Prozorov and Giannetta (beware of two errors in Eq. (15))
Movie of vortices and anti-vortices moving into the edges of a (left to right) DC-current-carrying superconducting strip in COMSOL/TDGL by Khaled Keshk (UMD). The GL order parameter magnitude is plotted as a function of position and time in the transient startup. Note the vortex/anti-vortex annihilation events at the center of the strip.
