Dhw formalism
http://fullformbook.com/Community/dhw 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.
