    • One can easily check that the derivation of Eq. (9) is valid not only for a Wigner crystal, but for any translation-invariant model of interacting electrons.

    • 2/h, but this value is still independent of the electron density. The reduction of the quantized value was attributed to the imperfect coupling of the wire to the leads (Ref. 50).

    • note
    • It is worth mentioning that the violation of the spin-charge separation in Eq. (30) is due to the inhomogeneity of the system. In the homogeneous case J = const, and the spin-charge separation is restored.

    • note
    • The standard solution (Ref. 60) applies the WKB approximation to the ground states of the oscillatory potentials near the minima of U(x). As a result it underestimates the level splitting (A4) by a factor (Ref. 62) of √π/e ≈ 1.075.
