Abstracts:
The generation of entangled states and their degree of
entanglement are studied in a relativistic formulation for the case of
two interacting spin-1/2 charged particles. In the realm of quantum
electrodynamics, we revisit the interaction that produces entanglement
between the spin components of covariant Dirac spinors describing the
two particles. In this way, we derive the relativistic version of the
spin-spin interaction, widely used in the nonrelativistic regime.
Following this consistent approach, the relativistic invariance of the
generated entanglement is discussed.
