Shwinger limit
WebThis is the so-called Schwinger limit, developed by Julian Schwinger in 1951, and works out to be 10 18 V m −1. This value is surpassed routinely in supernovae and other … WebMay 24, 2024 · To appreciate the effects of the electric charge in the structure of the star, we found that it must be in the order of $$10^{20}\,[\mathrm{C}]$$ with which the electric field is about $$10^{16}\,[\mathrm{V/cm}]$$ . For white dwarfs with electric fields close to the Schwinger limit, we obtain masses around $$2\,M_{\odot }$$ .

WebIn quantum electrodynamics (QED), the Schwinger limit is a scale above which the electromagnetic field is expected to become nonlinear. The limit was first derived in one of QED's earliest theoretical successes by Fritz Sauter in 1931 and discussed further by Werner Heisenberg and his student Hans Heinrich Euler. The limit, however, is commonly named …
