    • In contrast to Ref., we use a two-dimensional (2D) cutoff qmax =μ/ℓ in the integration over momentum q in Eq. (2) of Ref. and adjust μ=1/3 to obtain the mobility edge in the infinite medium at kℓ=1. The need for a cutoff arises from the failure of the small- q approximation implied by Eq. (1) of Ref. for q>1/ℓ (small distances). The exact way of applying the cutoff (2D or three-dimensional cutoff, exact value of μ, etc.) does not affect scaling with (large) L as far as the cutoff is consistent with the definition of the mobility edge.
