MAJORANA-INTERACTION IMPACT ON COLLAPSE STATES IN GRAPHENE P-N JUNCTIONS

Grushevskaya H. V., Krylov G. G.

Electronic structure of electrostatically confined graphene quantum dots is simulated within the framework of the quasi-relativistic graphene model. The confinement of vortex topologically-nontrivial graphene charge carriers in a hexagonal graphene p-n-junction region under an action of an external electrostatic superlattice potential has been revealed. The existence of steady atom-like localized bound Majorana states and confinement of collapse states through Majorana resonances of Klein scattering are explicitly demonstrated.
