Linked cell list method

In recent years, Verlet lists have often been supplanted by (or combined with) the Linked Cell List method [7], For discussion of these techniques, see [86, 173, 303, 307], See also [49, 50, 203, 335, 341] for work on fast parallel computation of molecular forces. 

The possibility of application of linked-lists method with cubic cells for noncubic periodic boxes is the great advantage of using the checker-board PBC. We present following the translation... 

Because we are interested in systems with rather short-range interactions with a well-defined cut-off, it is inefficient to examine all of the pairs of particles ij at each time-step to determine which ones have a nonzero force between them. An alternative is to divide the simulation cell into smaller cells of size r< -t- r, where is a small skin of order 0.3-0.5ct. Now one simply has to check pairs within neighboring cells to determine which pairs ij have a nonzero force. The extra skin allows one to create a list of neighbors, which only has to be updated every 10-20 time steps. Combining the link cell with a Verlet neighbor table is the most efficient method for doing any off-lattice simulation with short-range interactions. To obtain...
