Schwinger production
WebIn quantum electrodynamics(QED), the Schwinger limitis a scale above which the electromagnetic fieldis expected to become nonlinear. The limit was first derived in one of … The Schwinger effect has never been observed due to the extremely strong electric-field strengths required. Pair production takes place exponentially slowly when the electric field strength is much below the Schwinger limit, corresponding to approximately 10 V/m. With current and planned laser facilities, … See more 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 … See more • Schwinger limit • Vacuum polarization • Uehling potential • Euler–Heisenberg Lagrangian • MoEDAL experiment See more
