Query: Classifying superconductivity in Moir\'e graphene superlattices   Several research groups have reported on the observation of superconductivity
in bilayer graphene structures where single atomic layers of graphene are
stacked and then twisted at angles $\theta$ forming Moir\'e superlattices. The
characterization of the superconducting state in these 2D materials is an
ongoing task. Here we investigate the pairing symmetry of bilayer graphene
Moir\'e superlattices twisted at $\theta$ = 1.05{\deg}, 1.10{\deg} and
1.16{\deg} for carrier doping states varied in the range of n=0.5-1.5 10^(12)
cm^(-2) (where superconductivity can be realized) by analyzing the temperature
dependence of the upper critical field Bc2(T) and the self-field critical
current Jc(sf,T) within currently available models for single- and two-band s-,
d-, p- and d+id-wave gap symmetries. Extracted superconducting parameters show
that only s-wave and a specific kind of p-wave symmetries are likely to be
dominant in bilayer graphene Moir\'e superlattices. More experimental data is
required to distinguish between the s- and remaining p-wave symmetries as well
as the suspected two-band superconductivity in these 2D superlattices.
