The asymptotic shape conjecture for effective-resistance balls in the square lattice

Let rr be an i.i.d. resistance configuration on the edges of Z2\mathbb{Z}^2, and write Rr(0v)\mathcal{R}_r(0\leftrightarrow v) for the effective resistance between 00 and vv. Define

Bt=vZ2:Rr(0v)t.B_t=\\{v\in\mathbb{Z}^2: \mathcal{R}_r(0\leftrightarrow v)\leq t\\}.

Asymptotic shape conjecture. There exists a nonempty compact subset B0B_0 of R2\mathbb{R}^2 such that, for every positive number ε\varepsilon,

(1ε)B01logtBt(1+ε)B0.(1-\varepsilon)B_0\subseteq \frac{1}{\log t}B_t\subseteq (1+\varepsilon)B_0.

The claim predicts an asymptotic shape for effective-resistance balls, analogous to the time constant and limit shape in first-passage percolation. The source presents the existence of the time constant and asymptotic shape as believed but does not provide a resolution.
