Abstract:

In this talk I would discuss how superconducting junctions can be used as
phase sensitive detectors for Dirac and Majorana fermions. With a brief
introduction to the physics of Dirac like materials, i.e materials whose
low energy excitations obey an effective Dirac equation viz. graphene, I
would discuss the transport and dynamics in superconducting junctions of
such materials.  In the second part of the talk, I would discuss dynamics
in a superconducting junction with effective p-wave pairing amplitude and
show that analysis of the current-voltage characteristics reveals robust
phase-sensitive signatures for existence of Majorana quasi-particles in
such junctions.
