Percolation on patchwise heterogeneous surfaces under equilibrium conditions

Giménez, M.C.; Ramirez-Pastor, A.J.; Nieto, F. - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 26, pp. 6526-6534

The site percolation problem on square lattices whose sites are grouped in two types of energetically different patches is studied. Several lattices formed by collections of either randomly or orderly localized and no overlapped patches of different sizes are generated. The system is...
