fixed notation, since the elements of the Delta matrix are just complex numbers, and not matrices themselves.

a couple spelling changes, and a grammar changes to get over the 6 char limit.

| Mar 18, 2019 at 20:53 | comment | added | Alex Meiburg | @FraSchelle "There is no known p-wave superconductor to date." I was under the impression that Sr2RuO4 was p-wave. (Now that we're in 2018, we might say that graphene is, too.) | |
| Jul 1, 2018 at 19:01 | comment | added | Zhiqiang Wang | @cleanplay Whether you have $k_x+i k_y$ or some other linear function of $k_x$ and $k_y$ depends on crystal symmetries and energetic considerations (which pairing state saves more free energy in superconducting state, given a specific pairing mechanism). In principle they are all allowed. | |
| Sep 20, 2017 at 9:07 | comment | added | FraSchelle | @cleanplay As I say in my answer, the Cooper pairing problem is the same as the composition of two electronic (spin=1/2, and so fermionic statistics) angular momenta. Everything follows from this. | |
| Sep 19, 2017 at 14:26 | comment | added | cleanplay | FraSchelle, can you shed some light on why does one have $k_x+ik_y$ instead of some other linear function of $k_x$ and $k_y$ like $k_x+k_y$? I know you mention the Spherical harmonics- so it is just because you want to say that Cooper pairs are assumed to have a well-defined quantum number, or in other words, Cooper pair angular momentum commutes with the superconducting Hamiltonian? | |
