Dhw formalism
Webimportantly, the DHW formalism gives access to the rela-tivistic phase-space distribution of the produced particles. In the following, we present a brief outline of the DHW formalism for completeness. A convenient starting point is the gauge-invariant density operator of two Dirac field operators in the Heisenberg picture Cˆ αβ(r,s)=U(A,r,s ... WebThe DHW formalism is a relativistic phase-space quantum kinetic approach Vasak:1987um that has been now widely adopted to study the pair production from QED vacuum in strong background field. In the following, we present a brief review of the DHW formalism.

Based on the Dirac-Heisenberg-Wigner (DHW), formalism we derive a system of partial differential equations of infinite order for the sixteen irreducible components of the Wigner function. …
WebPhysical Review Journals 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.
