Apparent power-law behavior of conductance in disordered quasi-one-dimensional systems

Abstract
Dependence of hopping conductance on temperature and voltage for an ensemble of modestly long one-dimensional wires is studied numerically using the shortest-path algorithm. In a wide range of parameters this dependence can be approximated by a power-law rather than the usual stretched-exponential form. Relation to recent experiments and prior analytical theory is discussed.
