Nutation effect in a system of coherent excitons, photons, and biexcitons in the region of the M band
Khadzhi P.I. , Moskalenko S.A., Belkin S.N.
The mechanism coherent conversion of excitons and photons into biexcitons and back to excitons and photons in the region of the M luminescence band of the semiconductors is investigated. It is shown that the conversion rate depends greatly on the initial state of the system.
