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 … WebMar 26, 2024 · avors of Schwinger bosons on each site, created by the canonical operator sy i , with =";#, and j0iis the vacuum with no Schwinger bosons.
