WebMar 6, 2006 · Hereafter, a propagator description of the space-time emission of a polychromatic photon from an atom is presented, paying particular attention to the near-field electrodynamics. When the atom is embedded in a solid-state plasma the photon emission process can be dramatically modified. WebDec 8, 2024 · 1 Answer. Sorted by: 4. Yes and no. It takes a finite time for a given amount of energy to emerge, and the emission process is continuous in time. While the emitter and photon are still interacting, you can't really imagine the photon as an independent thing. …

Because the four devices do not have the same readout time, we measure the localization accuracy with respect to the integration time. The results are shown on Fig. 5. … WebMar 18, 2024 · Conclusions. We have proposed a measure of localization for the photon, the expectation of the electromagnetic field strength in a coherent wavepacket state of mean photon number unity related to a one-photon state. We considered two test states. The …
