Resonant states in graphene: Interplay with magnetic field and spin orbit coupling — •Jeongsu Lee, Denis Kochan, and Jaroslav Fabian — Institute for Theoretical Physics, University of Regensburg, 93040 Regensburg, Germany

A vacancy or an adatom in graphene induces π-magnetism and resonant scattering. Even without the magnetism in consideration, the resonant phenomenon can exhibit interesting physics when combined with an external magnetic field. A strong magnetic field in graphene induces Landau levels overlapping with the resonance peak near the Dirac point. As a result, the resonant state splits into two bound states with effective magnetic momenta of opposite sign. Employing realistic tight-binding parameters, we theoretically investigate the interplay between resonance scattering and the magnetic field in the presence of the magnetic moment and local spin-orbit coupling.
