The second of these approaches applied to molecules has been dealt with in the review by Wilson (1981). Therefore that ground will not be covered in this chapter. However, there has been much progress using the so-

It will be useful, by way of introduction, to extend the zero-field discussion by giving a brief summary of the main physical properties of the elec

Quantum Monte Carlo Calculation of Correlation Energy,e Carlo (DMC) method, one is directly concerned with the evolution in imaginary time of the wave function, which corresponds to a diffusion process in configuration space. In the Green Function Monte Carlo (GFMC) technique, on the other hand, a time-integrated form of the Green function or resolvent
