Abstract
We present Monte Carlo estimates for site and bond percolation thresholds in simple hypercubic lattices with 4–13 dimensions. For they are preliminary, for they are between 20 and times more precise than the best previous estimates. This was achieved by three ingredients: (i) simple and fast hashing that allowed us to simulate clusters of millions of sites on computers with less than 500 Mbytes memory; (ii) a histogram method that allowed us to obtain information for several p values from a single simulation; and (iii) a variance reduction technique that is especially efficient at high dimensions where it reduces error bars by a factor of up to and more. Based on these data we propose a scaling law for finite cluster size corrections.
