    • In particular, the commonly cited "exception" to the theorem - the one-dimensional Hubbard model with next-nearest-neighbor hopping [19,20] - has physical meaning only if the electrons are allowed to bypass the nearest site and hop to the next one by using a second dimension.

    • note
    • Unlike the case of higher dimensions, the long-range order in a one-dimensional Wigner crystal is smeared by quantum fluctuations, and only weak density correlations remain at large distances [22]. On the other hand, the coupling of electron spins is controlled by electron interactions at distances of order 1/n (see also [23]), where the picture of a one-dimensional Wigner crystal is applicable.

    • note
    • The contribution of the spectator electrons saturates rapidly as their number is increased. This indicates that the destruction of long-range order in the quasi-one-dimensional Wigner crystal by quantum fluctuations will not affect our conclusions.
