Shwinger limit
WebOct 23, 2024 · Main page: Physics:Schwinger limit. Quantum corrections to Maxwell's equations are expected to result in a tiny nonlinear electric polarization term in the vacuum, resulting in a field-dependent electrical permittivity ε deviating from the nominal value ε 0 of vacuum permittivity. WebJan 4, 2024 · At \(10^{24}\ \mathrm{Wcm^{-2}}\), a Lorentz factor of \(\gamma \sim 10^5\) is required to reach the Schwinger limit. This is the reason why quantum electrodynamics effects and in particular strong- field pair generation is accessible with the extreme-intensity lasers (multipetawatt lasers).

WebSchwinger Limit Edit Edit source History Talk (0) One of the revolutionary ideas from quantum electrodynamics is the Dirac sea. According to this view, vacuum is not empty, but actually filled with negative energy electrons and positrons. Particles in the Dirac sea cannot ... WebNote, if the cylindrical cavity is replaced by a spherical one, based on another physical concept referred to as microbubble implosion [32 – 35], ultrahigh electric fields may be obtained close to the Shwinger limit instead of an ultrahigh magnetic field.

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, this is an unfeasibly strong electric-field strength, so various mechanisms have been proposed to speed up the process and thereby reduce the electric-field strength required for its o…
