Entanglement Negativity of Spin-Orbit Correlations in a general Qubit-Qudit Setup
For any pure qubit-qudit state, the negativity of the partial transpose equals the square root of the determinant of the two-by-two reduced density matrix, which the paper applies to spin-orbit entanglement in protons.
