Abstract
In this talk I would discuss how superconducting junctions can be used asphase sensitive detectors for Dirac and Majorana fermions. With a briefintroduction to the physics of Dirac like materials, i.e materials whoselow energy excitations obey an effective Dirac equation viz. graphene, Iwould discuss the transport and dynamics in superconducting junctions ofsuch materials. In the second part of the talk, I would discuss dynamicsin a superconducting junction with effective p-wave pairing amplitude andshow that analysis of the current-voltage characteristics reveals robustphase-sensitive signatures for existence of Majorana quasi-particles insuch junctions.
