Three-electron bunches in occupation of a 5-site Coulomb cluster
R. E. Putnam, M. E. Raikh
Attraction of like charges in a localized system implies that, upon increasing the Fermi energy, the occupation of the system changes as, n\rightarrow (n+2), while the occupation,…
Damping of the Franz-Keldysh oscillations in the presence of disorder
R. E. Putnam, M. E. Raikh
Franz-Keldysh oscillations of the optical absorption in the presence of short-range disorder are studied theoretically. The magnitude of the effect depends on the relation between…
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…
