2 fold symmetry has been shown to exist in the normal state of CsV3Sb5 despite 6 fold crystal symmetry[1]
Perhaps we may be able to see a similar symmetry in the superconducting gap? Why would we?
Perhaps we may be able to see a similar symmetry in the *large enhancement of K with small fields (10% Hc2)* [2]
- ~ Should we do K(0,theta) & K(100 Oe, theta) at low temperatures then?
- ~ Or K(0,T) for select angles to look at the gap?
Another question: what is the origin of violating Weiderman-Franz law by 20%? Is this common?
