Josephson current in wave pairing superconductor graphene junctions

We study the Josephson current in p wave pairing superconductor–normal metal–superconductor (SNS) graphene junctions at the finite temperature using the Dirac Bogoliubov–de Gennes (DBdG) formalism. It is found that the energy levels of the Andreev bound states and the Josephson current depend on the p wave pairing symmetry. The position of the maximum current is shifted to the left by increasing the temperature and the dc Josephson current shows a simple sinusoidal dependence on the phase in the p x wave symmetry SNS graphene junction at higher temperatures. The Josephson current displays an oscillating decay as a function of the length L and the period of oscillation of the Josephson current does not change by increasing the temperature.
