Unified Model for Pseudononuniversal Behavior of the Electrical Conductivity in Percolation Systems
1The Racah Institute of Physics, The Hebrew University, Jerusalem 91904, Israel.
Abstract:
Many values of the observed conductivity percolation exponent t cannot be explained by the classical universal theory or by the existing nonuniversal theories. In particular, the 1.3≤t≤4.0 clustering of t values, in both composite materials and porous media has not been accounted for. In this work we were concerned with a pseudononuniversal percolation behavior that, unlike the genuine nonuniversal behavior, explains the statistics of the experimentally observed percolation conductivity exponents in continuum systems.

Electrical Conductivity
In a practical conductor, an applied electric field may be sustained, causing a flow of electrons, which produce a current. The differential form of the current, the current density, is related to the electric field.
More generally, it is related to the force per unit charge, which involves the...
Theory of Metallic Conduction
In this theory, Newton's second law of motion is used to determine the acceleration of an electron in the presence of an applied electric field. Then, its velocity is expressed via this acceleration.
