Long Range Interactions

Formally a potential is defined to be short ranged if it decreases with distance  r quicker or similar than  \frac{1}{r^{d-1}} where  d is the dimensionality of the system. Electrostatic, gravitatory and dipolar interactions, present in many physical systems, are examples of long range interactions.

How to mimic the effects of Long Range interactions in Simulations

Currently, numerical simulations are playing a main role in explaining and unravelling the rich variety of new, and unexpected behaviours found in recent theoretical and experimental studies about these electrostartic systems. ... http://cmt.dur.ac.uk/sjc/thesis_dlc/node61.html


Use of Periodic Boundary Conditions in Simulations

Frequently, periodic boundary conditions are used in these simulations in order to approach bulk systems within the limits of currently available computers.
