We find that while the thermal conductance displays the usual exponential dependence on temperature, reflecting the s -wave symmetry of the superconducting graphene, it exhibits an unusual oscillatory dependence on the potential h...<br/>[Phys.

Due to the spontaneously broken time-reversal symmetry, the effective action of the system contains an anomalous term not present in conventional superconductors.
