SchwingerEffekt
The Schwinger-Effekt, also known as the Schwinger effect, is the non-perturbative production of electron-positron pairs from the quantum vacuum in the presence of a strong electric field. It was predicted within quantum electrodynamics by Julian Schwinger in 1951. The effect reflects the instability of the vacuum when subjected to intense fields, causing vacuum fluctuations to become real particles.
In a constant, uniform electric field, the vacuum can be regarded as a medium in which virtual
Historically, the Schwinger effect is regarded as a quintessential non-perturbative prediction of quantum electrodynamics, inaccessible by
