Abstract
In this paper the authors study how the entanglement of electron's spin and orbital degrees of freedom depends on the atomic spin-orbit coupling. They explain that for large spin-orbit coupling the system ground state can either still show negligible spin-orbital entanglement or can evolve to a highly spin-orbitally entangled phase with completely distinct properties.
