    • Straley and Kenkel investigated random resistor networks with nonlinear I-V characteristics [J.P. Straley and S.W. Kenkel, Phys. Rev. B 29, 6299 (1984)]. They showed that far from the percolation threshold the averaged I-V characteristic is similar to the I-V characteristic of the individual network element, whereas a power law behavior prevails close to (Formula presented). For the special case of power law I-V characteristics V=r|I(Formula presented)sgnI they found the critical exponent t in two dimensions to be only weakly dependent on the exponent a. Roux and Herrmann investigated two-dimensional resistor networks with individual circuit elements that had random voltage thresholds and obtained a power law behavior of the averaged I-V characteristic at the percolation threshold [S. Roux and H.J. Herrmann, Europhys. Lett. 4, 1227 (1987)]. The existence of a universal power law in the I-V characteristics at (Formula presented) is commonly regarded as a signature of the vortex glass transition.
