D wave symmetry
WebJan 29, 2024 · High-Tc superconductors have d-wave symmetry meaning the wavefunction has four "lobes" (in k-space). This means the properties (the "gap") of the superconductor will depend on the orientation of the crystal. P-wave … WebSeveral experimental and theoretical arguments have been made in favor of a d-wave symmetry for the superconducting state in some Fe-based materials. It is a common belief that a d-wave gap in the Fe-based superconductors must have nodes on the Fermi surfaces centered at the Γ point of the Brillouin zone. Here we show that, while this is the ...

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. WebWhen loaded with four fermions, the ground state is d-wave symmetric; when loaded with two fermions, the ground state exhibits S-wave symmetry. Consequently the two states …
