Dark excitons lighten up in a magnetic field

Dark excitons lighten up in a magnetic field

The luminescence spectrum of excitons in ReS2 resembles the transitions in a free atom (Rydberg series), except that some transitions are missing, they are “dark”. This is due to interactions, as detailed by the theoretical calculations of A. Slobodenyuk, and verified by measurements in magnetic fields. More details in the paper.
