22. The ratio (Equation presented) would be related to the effective mass in the case of single-band superconductors without the Pauli paramagnetic effect, but its interpretation in multiband superconductors such as (Equation presented)(Equation presented) is not straightforward.

25. The critical current density in a superconductor sometimes shows an anomalous peak just below (Equation presented), indicating an enhancement of the pinning force acting on vortices. This is called the peak effect. Although its origin is not yet completely understood, it is broadly associated with an order-disorder transition of a vortex lattice. See, for example, T. Giamarchi and S. Bhattacharya, arXiv:cond-mat/0111052.
