34. For M qubits, the set of product state is defined as (Formula presented)
35. For compactness, we have truncated our numerical results after the third or fourth decimal. If desired, much higher precision can be obtained with our numerical algorithm.
36. In the special case where (Formula presented) this can be demonstrated by applying the same procedure as for the Heisenberg interaction, showing that the corresponding four equations have no solution.
37. The spin-orbit coupling (Formula presented) for a band electron in a slowly varying potential V contains both the bare mass (Formula presented) (from the magnetic moment of the electron) and the effective mass m (since the velocity of the electron is derived from the band structure). In our case, the effective mass is canceled because (Formula presented)
