## Abstract The diffusion QuantumβMonteβCarlo method is applied to a set of coupled oscillators as a first approach to a polyethylene chain. The obtained energy eigenvalues are in good agreement with normal mode analysis. For chains shorter than 50 atoms a distinction between center oscillators and

A fast algorithm for simulating one-dimensional quantum spin systems on CRAY 1 computers is presented. Various versions of the algorithm suitable for general spin xxz and xyz models with and without magnetic field are discussed.
Monte Carlo simulations have been carried out on DNA oligomers using an internal coordinate model associated with a pseudorotational representation of sugar repuckering. It is shown that when this model is combined with the scaled collective variable approach of Noguti and Go, much more efficient si

## Abstract We have tested and compared several (pseudo) random number generators (RNGs) applied to a practical application, ground state energy calculations of molecules using variational and diffusion Monte Carlo metheds. A new multiple recursive generator with 8thβorder recursion (MRG8) and the
