Long-range interactions

13.1 Introduction

The systems examined so far have been based on interactions whose range is comparatively short. Short-range forces exclude a very important group of problems involving electric charges and dipoles; in systems of this type the central role of the long-range forces cannot be neglected. Long-range interactions, which, by definition, are not truncated and therefore extend over the entire system, inherently require O () computational effort. This requirement clearly precludes the treatment of large systems directly and has lead to the development of alternative approaches that are able to deal with the problem ...
