A renormalisation group approach for two-dimensional site percolating system

Abstract

A renormalisation group approach is applied to the square site percolating system using a scaling transformation of a finite lattice in real space. The scale of length b for renormalisation has been changed for b=2, 3 and 4. For each scale of length, the location of the fixed point and the correlation length critical exponent are calculated and listed in tabular form.
