    • Although (4) can be solved analytically in the small-J limit as a one-dimensional ``potential'' problem on the half-line l >= 0, it is not possible in more than one physical dimension to write any simple Schrödinger equation in terms of the hole position, r vec, alone. In particular H = -2 sqrt 3 w - w del2+ Jr is incorrect since for a random walk r app l1/2 and the potential energy is linear in l, not r.
