WebApr 5, 2024 · This is a general feature of the DHW formalism, where positrons can be viewed as electrons moving backward in time. In particular, for a non-relativistic non-degenerate Maxwellian particle beams of electrons, with a distribution ∝ exp ( − ( p − p b z ) 2 / p t 2 ) , we must use a distribution ∝ exp ( − ( p + p b z ) 2 / p t 2 ) for a ...

Webparticles involved [47, 48]. Such a formalism based on suitable real-time correlation functions is indeed avail-able and has already been studied in the context of pair production [49]. The present work is devoted to explor-ing this DHW formalism, putting it into the context also of other work such as quantum kinetic equations, and WebIII. THE DHW FORMALISM The DHW formalism is one of the quantum kinetic approaches that is widely adopted to study vacuum pair production in multidimensional electromagnetic fields [36,37]. It enables one to obtain phase space information about the particles created in vacuum, so that much can be learned about Schwinger pair production process. list of gujarati movie
