48. The Fermi velocities in Ref. [3] were estimated from an upper critical field analysis assuming a single-band Ginzburg-Landau and BCS theory.
49. Recently, Iwasawa (Ref. [63]) have presented a more involved discussion regarding estimating (Equation presented) in systems with significant correlation effects. Adopting their approach does not change our discussion significantly, as shown in Appendix.
