    • s there is also the possibility that various other types of non-Fermi liquid states, distinct from those discussed here, could occur. None of these subtleties are relevant for the present discussion.

    • note
    • All crystalline phases with an integer number of electrons per unit cell will here be called a "Wigner crystal" although this may actually refer to a host of distinct phases, which differ both in crystal (Ref. 18) and magnetic (Ref. 23) structure.

    • note
    • Existence of a supersolid phase in He crystals has not been proven. Existence of vacancies in the ground state in this case is of a quantum mechanical nature while on our case the existence of the liquid droplets embedded into the liquid is a consequence of the electrostatics.
