Experimental studies of quantum critical

1. The prototypical non-Fermi-liquid (NFL)
superconductor CeCu2Si2 shows a quantum
phase transition (QPT) of itinerant (SDW) nature.
Q Does the same hold true for all NFL
heavy-electron superconductors? 2. The NFL metal
YbRh2Si2 exhibits a QPT of local (-moment)
nature. Even single crystals of highest
purity are not superconducting. Q Are
local quantum critical fluctuations unfavorable
for superconductivity?
