A function with half-wave symmetry does not have to be even … WebSep 19, 2014 · The chiral d -wave superconducting state in graphene is a spin-singlet -wave state. Due to the sixfold symmetry of the honeycomb lattice, the two d -wave states carry an equal weight but have a relative π /2 phase shift. This results in a fully gapped bulk superconducting state at any finite doping level in graphene.
WebFeb 15, 2002 · This suggests that d-wave order parameter symmetry predominates with little, if any, imaginary component (<5%) over the entire temperature range. A similar conclusion was reached recently by studying the critical current of 0–45° asymmetric bicrystal grain boundary junctions [29].
