Dynamic Fano Resonance of Quasienergy Excitons in Superlattices
arXiv:cond-mat/0006276 · doi:10.1088/0953-8984/12/50/103
Abstract
The dynamic Fano resonance (DFR) between discrete quasienergy excitons and sidebands of their ionization continua is predicted and investigated in dc- and ac-driven semiconductor superlattices. This DFR, well controlled by the ac field, delocalizes the excitons and opens an intrinsic decay channel in nonlinear four-wave mixing signals.
