Title: Percolation with a threshold at zero: A new universality class

The model is in a different universality class from ordinary percolation, despite the fact that it is defined by a potential with only short-range correlations. The conductivity exponent ${t}_{0}$ in two dimensions is calculated in terms of static percolation critical exponents, including a nonstandard exponent x. Static critical exponents are also given in general dimensions. The model may provide a useful description of the pore space of some rocks, which appear to have a percolation threshold at or near zero.Read More
