Path Integral Simulations of Excess Electrons in Condensed Matter
Numerical methods constitute a powerful way of simulating and having insight into systems which are too complex to be dealt with analytically. Some of the numerical methods used in classical systems are described in this volume (see chapters by Haneef). Such methods are applicable provided that quantum effects such as tunnelling (i. e. the penetration of particles into classically forbidden regions) or exchange between the different particles can be neglected.
