The statistics of a system of four boson modes in Stokes-Antistokes interaction is considered with respect to the influence of damping in one mode. The time evolution of the system is calculated. The mean particle numbers and the factorial moments of photon number distribution are calculated. Sunierical results show strong dependence on bath temperature but only weak influence of the bath coupling strength. In the combined Stokes-Antistokes system Antibunching appears if the bath temperature is low.
The exciton-photon interaction in a semiconductor-optical device is influenced by the carrier pair density. To take this into account, the coupling constant is corrected to the first order. This simple model shows remarkable dynamical behaviour as, for instance, up to five coexisting fixed points and chaos. Chaotic transients are found which are precursors of permanent chaotic motion.Die Exziton-Photon-Wechselwirkung in einer halbleiter-optischen Anordnung wird durch die Tragerpaardichte beeinfluRt. Deshalb wird in einem einfachen Modell die Kopplungskonstante durch einen Term erster Ordnung in der Tragerdichte erganzt. Zu den bemerkenswerten dynamischen Eigenschaften dieses Systems gehoren bis zu funf koexistierende Fixpunkte und Chaos. Transientes Chaos zeigt sich als Vorlaufer permanent chaotischer Bewegung.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
