BaFe2(As1-xPx)2: a QCP inside the superconducting dome?
• Is a peak in the penetration depth a signature of a QCP?
Levchenko et al, PRL 110, 177003 (2013)Chowdhury et al, PRL 111, 157004 (2013)
far from trivial…
• Why no peak in Ba(Fe1-xCox)2As2?
• Why a single quantum phase transition (compare with high-T)? very weak simultaneous 1st-order nematic-magnetic transition
