Long-living excited states of a 2D diamagnetic exciton
R. E. Putnam, M. E. Raikh
Hydrogenic excited states of a 2D exciton are degenerate. In the presence of a weak magnetic field, the -states with a zero momentum of the center of mass get coupled to the …

Renormalization of the 3D exciton spectrum by the disorder
R. E. Putnam, M. E. Raikh
Effect of short-range disorder on the excited states of the exciton is studied. Disorder causes an obvious effect of broadening. Microscopically, an exciton, as an entity, is scatt…
