Zusammenfassung

We investigate percolation transitions in a nonlocal network model numerically. In this model, each node has an exclusive partner and a link is forbidden between two nodes whose \$r\$-neighbors share any exclusive pair. The \$r\$-neighbor of a node \$x\$ is defined as a set of at most \$N^r\$ neighbors of \$x\$, where \$N\$ is the total number of nodes. The parameter \$r\$ controls the strength of a nonlocal effect. The system is found to undergo a percolation transition belonging to the mean field universality class for \$r< 1/2\$. On the other hand, for \$r>1/2\$, the system undergoes a peculiar phase transition from a non-percolating phase to a quasi-critical phase where the largest cluster size \$G\$ scales as \$G N^\alpha\$ with \$= 0.74 (1)\$. In the marginal case with \$r=1/2\$, the model displays a percolation transition that does not belong to the mean field universality class.
