Generation and evolution of spin entanglement in nonrelativistic QED
Ru-Fen Liu, Chia Chu Chen
Abstract
Analysis of the generation of spin entanglement from nonrelativistic QED is presented. The results of entanglement are obtained with relativistic correction to the leading order of ${(v/c)}^{2}.$ It is shown that to this order, the degree of entanglement of a singlet state does not change under time evolution, whereas the triplet state can change.
