- Abstract: This work provides a comprehensive approach to analyze the entanglement
between subsystems generated by identical particles, based on the
symmetric/exterior algebra (SEA) and microcausality. Our method amends the
no-labeling approach (NLA) to quantify any type of identical particles'
entanglement, especially fermions with the parity superselection rule. We can
analyze the non-local properties of identical particles' states in a
fundamentally equivalent way to those for non-identical particles, which is
achieved by the factorizability of the total Hilbert space of identical
particles. This formal correspondence between identical and non-identical
particle systems turns out to be useful for quantifying the non-locality
generated by identical particles, such as the maximal CHSH inequality violation
and the GHJW theorem of identical particles.

We study space-time resolved densities of particle-hole pairs produced by an external time-dependent field acting on non-interacting non-relativistic particles.
It is shown that, at least in some cases, the densities are not affected by Fermi-Dirac or Bose- Einstein statistics, and are determined only by the initial state of the multi-particle system.
