Web14 Nov 2008 · The Schwinger mechanism, the production of charged particle-antiparticle pairs in a macroscopic external electric field, is derived for 2+1 -dimensional theories. WebElectromagnetism is one of the four fundamental forces of nature. The others are gravity, and the strong and weak interactions of particle physics. [1] The electromagnetic force pushes or pulls anything that has an electric charge, like electrons and protons. It includes the electric force, which pushes all charged particles, and the magnetic ...

The thermal gauge field theories have been constructed and used in quantum field-theoretical phenomena [13–17] and mainly summarized in imaginary- [18] or real-time [19] form. For thermal correction to Schwinger pair production, various methods obtain identical results at WebSchwinger pair production can be formulated as a vacuum decay process. In this case the so-called false vacuum, jΩi, is the vacuum state in the absence of the external field. It contains no charged particles. ofgem chief data officer

Web16 Jul 1994 · Schwinger was one of the inventors in the 1940s of the theory of renormalization, mentioned above. This theory allows individual particles to be considered from a distant viewpoint. Virtual particle pairs are not considered individually but rather surrounding virtual particles influence the appearance of the original particle. Web18 Nov 2024 · Electron–positron pair production in the strong-field regime (Schwinger mechanism) has never been observed experimentally.

Web19 Jun 2012 · It is shown that the Schwinger production rate can be eventually suppressed by the increasing attractive gravitational force as the geometry changes from the extremal to the near extremal black hole. Consequently, the Schwinger mechanism and the Hawking radiation are generically indistinguishable for the near-extremal black holes.
