The possibility of p-wave pairing in superconductors has been proposed more than five decades ago, but has not yet been convincingly demonstrated. One difficulty is that some p-wave states are thermodynamically indistinguishable from s-wave, while others are very similar to d-wave states. Here we studied the self-field critical current of NdFeAs(O,F) thin films in order to extract absolute values of the London penetration depth, the superconducting energy gap, and the relative jump in specific… Expand
Classifying superconductivity in Moiré graphene superlattices
TLDR
Extracted superconducting parameters show that only s -wave and a specific kind of p -wave symmetries are likely to be dominant in bilayer graphene Moiré superlattices, and more experimental data is required to distinguish between the s - and remaining p - waves as well as the suspected two-band superconductivity in these 2D superlATTices.

Chiral superconductors.
TLDR
The current theory and experimental results on chiral superconductors are discussed, focusing on two of the best-studied systems, Sr2RuO4, which is thought to be a chiral triplet p-wave superconductor, and UPt3, which has two low-temperature superconducting phases (in zero magnetic field), the lower of which is believed to be chiral doublet f-wave.
