Optical detection of Majorana fermions via a quantum dot — •Luzie Weithofer, Anders Ström, and Patrik Recher — Institute of Mathematical Physics, TU Braunschweig, 38106 Braunschweig, Germany

The search for Majorana bound states (MBS) in condensed matter systems is currently in the center of attention for theorists and experimentalists alike. Shortly after MBS have been predicted to emerge in “Majorana nanowires” [1,2], several experiments have indeed reported potential signatures of MBS. While these experiments concentrate on conductance measurements, here, we discuss the novel possibility of detecting MBS optically via their coupling to a quantum dot with a sufficiently strong dipole moment.
