Optical Poincare sphere rotations $e^{-i\theta\sigma_{x}/2}$ , $e^{-i\theta\sigma_{y}/2}$ and $e^{-i\theta\sigma_{z}/2}$ can be realized by wave-plate combinations. Errors due to combinations with non-ideal wave plates are discussed for three specifi

Recently a quantum teleportation scheme has been analyzed by Wangner et al. (J. Opt. Soc. Am. B 27:A73–A80, 2010) which is based on spatially and temporarily resolved collective spontaneous emission. We study a similar model, which has the two atom

With the occurrence of an adding driving field, the properties of the dispersion and the absorption of a four-level system are changed greatly. The system can produce the normal and anomalous dispersion regions with proper parameters. Here, the drivi

Measurement of obvious negative capacitance (NC) at large forward bias of light-emitting diodes (LEDs), using an alternating current (AC) small signal, together with direct current (DC) I-V plot, has shown that the NC grows exponentially with the for

In order to explain the phenomenon of negative capacitance (NC) in light emitting diodes LEDs, we present a new model based on local strong recombination in active region and firstly deduce the analytic expression of NC from continuity equation. The

The experimental study on negative capacitance (NC) of various light-emitting diodes (LEDs) is presented. Experimental result shows that all LEDs display the NC phenomenon. The voltage modulated electroluminescence (VMEL) experiment confirms that the
