Query: Pairwise mode entanglement in Schwinger production of
  particle-antiparticle pairs in an electric field   Quantum entanglement is the characteristic quantum correlation. Here we use
this concept to analyze the quantum entanglement generated by Schwinger
production of particle-antiparticle pairs in an electric field, as well as the
change of mode entanglement as a consequence of the electric field effect on an
entangled pair of particles. The system is partitioned by using momentum modes.
Various kinds of pairwise mode entanglement are calculated as functions of the
electric field. Both constant and pulsed electric fields are considered. The
use of entanglement exposes information beyond that in particle number
distributions.
