21. Lanczos and quantum Monte Carlo methods do not have the energy resolution to resolve a soft gap of this size, and its existence in two dimensions is therefore not established.
22. Note that LHO-LHO alignment refers to the whole region ε 1 - U / 2 < ε 2 < ε 1 + U / 2 and not just the line ε 1 = ε 2, and similarly for LHO-UHO alignment.
