Ak. Rotaru et Kv. Shura, DYNAMIC OPTICAL CHAOS OF COHERENT EXCITON S AND BIEXCITONS IN SEMICONDUCTORS, Zhurnal eksperimental'noj i teoreticheskoj fiziki, 104(1), 1993, pp. 2374-2387
A possibility for appearing the ultrashort dynamic chaos in the system
of coherent excitons, photons and biexcitons in semiconductors is pre
dicted. Depending on the magnitude of the exciton - biexciton conversi
on constant and initial quasiparticle concentration in the system, bot
h the regular and stochastic vibrations are shown to be possible. The
dynamic stochasticity of coherent quasiparticles is due to breaking do
wn the system's integrals of motion.
