Interatomic forces in condensed matter /

There is a continuing growth of interest in the computer simulation of materials at the atomic scale, using a variety of academic and commercial computer programs. Such programs work with very diverse models of the inter-atomic forces. This book explains how such models are constructed and their sci...
