Accretion-disk corona (ADC) is required from observational as well as theoretical reasons. In almost all of traditional studies, however, a stationary corona has been assumed; i.e., the corona gas corotates with the underlying (Keplerian) accretion disk, and the radial motion is ignored. Recently, in the theory of accretion disks a radiative interaction between the gas and the external radiation field has attracted the attention of researchers. In particular the radiation drag between the gas and the external radiation field becomes important from the viewpoint of the angular-momentum removal. We thus examine the effect of radiation drag on the accretion-disk corona above/below the accretion disk (Watanabe, Fukue 1996a, b). We suppose that an accretion disk can be described by the standard disk, and that radiation fields are produced by the central luminous source and the accretion disk, itself. In general an accretion-disk corona under the influence of strong radiation fields dynamically infalls (advected) toward the center.

The spontaneous emission rate of a two-level system quantum dots is not intrinsic properties of the emitter itself but is molded by the electromagnetic environment that surrounds it. Photonic crystal micro cavity can conveniently shape the states of electromagnetic modes by providing modes with the required small volumes and high quality factors. This paper studies spontaneous emission from quantum dots embedded in photonic crystal micro cavity, and introduces the coupling characters of photonic crystal and quantum dot, and analyses the effectiveness of spontaneous emission enhancement from quantum dots embedded in photonic crystal micro cavity in detail. The research of this paper provides a basic reference for dynamic control of optics quantum systems.
