We study numerically the production of orbital and spin entangled states in chaotic quantum dots for noninteracting electrons. The introduction of spin-orbit coupling permits us to identify signatures of time-reversal symmetry correlations in the entanglement production previously unnoticed, resembling weak-(anti)localization quantum corrections to the conductance.

Abstract
We study numerically the production of orbital and spin entangled states in chaotic quantum dots for noninteracting electrons. The introduction of spin-orbit coupling permits us to identify signatures of time-reversal symmetry correlations in the entanglement production previously unnoticed, resembling weak-(anti)localization quantum corrections to the conductance. We find the entanglement to be strongly dependent on spin-orbit coupling, showing universal features for broken time-reversal and spin-rotation symmetries.File in questo prodotto:
