Schwinger effect experiment
WebThe Schwinger effect is about creating an electron and a positron. The effect in this paper is about raising a preexisting electron in a solid from a lower energy level to a higher one. (They say this "creates a hole" because the lower energy level is no longer occupied.) Web16 Jul 1994 · Schwinger was one of the most important and influential scientists of the twentieth century. The list of his contributions is staggering, from his early work leading to …

In this scheme a greatly enhanced pair production rate is predicted, which also means a lower …
Web27 Mar 2024 · We represent a possible dosimetric effect of the interaction with laser light, inferring from experiments the characteristics of laser-assisted cross-sections. Using a Monte-Carlo calculation for simulating the micro-dosimetric aspects of the irradiation of a simple geometry, we show the need of new experimental data and more detailed … Web1 Nov 2024 · In order to see how back reaction modifies the Schwinger effect, we plot V t o t (x) versus x with α = 0.8 for different values of a in the left panel of Fig. 2.It is clearly seen that as a increases, the height and width of the potential barrier both decrease. As you know, the higher (or the wider) the potential barrier, the harder the produced pair escapes to …
