Conductance fluctuations in random resistor networks with hyperuniform disorder

Statistical Mechanics 2026-05-21 v2

Abstract

We study conductance fluctuations in random resistor networks with hyperuniform bond disorder, where the fluctuations of the number of bonds present in a test volume VV scale as VaV^{-a} with a>1/2a > 1/2. Since small changes in the concentration of bonds present in a local region give rise to a proportionate increase in the locally averaged conductance, one may expect that in hyperuniform disorder, conductance fluctuations will also show suppressed fluctuations. We argue that this is not the case: conductance fluctuations scale as Ld/2L^{-d/2} for a sampling size LL. We show numerical results for d=2d=2.
