Unified single-photon and single-electron counting statistics: From cavity QED to electron transport
A key ingredient of cavity QED is the coupling between the discrete energy levels of an atom and photons in a single-mode cavity. The addition of periodic ultrashort laser pulses allows one to use such a system as a source of single photons—a vital ingredient in quantum information and optical computing schemes. Here we analyze and time-adjust the photon-counting statistics of such a single-pho...
متن کاملCounting statistics of single electron transport in a quantum dot.
We have measured the full counting statistics of current fluctuations in a semiconductor quantum dot (QD) by real-time detection of single electron tunneling with a quantum point contact. This method gives direct access to the distribution function of current fluctuations. Suppression of the second moment (related to the shot noise) and the third moment (related to the asymmetry of the distribu...
متن کاملElectron Avalanche Statistics
Since the times of the founders of streamer theory — Raether [1], Loeb [2] and Meek [3] — a special attention has been paid to high populated electron avalanches possessing potential to overgrowing into streamers. One of the basic problem that has not been resolved so far concerns anomalous statistical behavior of big avalanches with electron populations n > 10. The mentioned anomaly consists i...
متن کاملPhotomultiplier Tubes
Light which enters a photomultiplier tube is detected and produces an output signal through the following processes. (1) Light passes through the input window. (2) Light excites the electrons in the photocathode so that photoelectrons are emitted into the vacuum (external photoelectric effect). (3) Photoelectrons are accelerated and focused by the focusing electrode onto the first dynode where ...
