The Schwinger effect is a predicted physical phenomenon whereby matter is created by a strong electric field. It is also referred to as the Sauter–Schwinger effect, Schwinger mechanism, or Schwinger pair production. It is a prediction of quantum electrodynamics (QED) in which electron–positron pairs are spontaneously created in the presence of an electric field, thereby causing the … pm kisan samman nidhi yojana rejected list 2021Web1 Introduction The Schwinger mechanism [1] is a non-perturbative phenomenon by which electron-positron pairs can be produced by a static electrical eld [1{3].
