However, in this paper, we suggest that the jitter radiation in our model is coherent. We provide two reasons. First, kinetic turbulence provides a perturbation field to jitter radiation in our scenario, and the jitter radiation can have emission in a small coherent length scale. diapered by my little sister https://a1fadesbarbershop.com

WebFor an incoherent mechanism, it is defined as that "the intensity (or luminosity) of radiation from the source is less or equal to the sum of the intensities of spontaneous emission from different parts of the source" and as "due to spontaneous emission when the corresponding absorption process is unimportant" . From these definitions, we come ... WebJul 22, 2011 · We study dynamics of a two-level superconducting quantum system, analogous to a natural atom in an open space, by measuring the evolution of its coherent and incoherent emission. The emitted waves containing full information about the states of the artificial atom are efficiently collected due to strong atom-transmission-line coupling. …
