Towards an Operational Quantum Memory,correlation, a very large number of configurations are needed. Accurate calculations even on small molecules can strain the power of the largest modern computers; and the resulting multiconfigurational wave functions are often so complicated that they are difficult to interpret.

uan tum chemists do. But it must be admitted, that in contrast to physicists and chemists, "quantum chemists" seem to be a rather ill-defined category of scientists. Quantum chemists are more or less physicists (basically theoreticians), more or less chemists, and by large, computationists. But fir

The Wavelet Transform: A New Mathematical Tool for Quantum Chemistry,ht into electronic distributions, e.g. information on the momenta of the electrons is completely smoothed out. Therefore the possibility of “looking at orbitals ” in different ways is still an up-to-date problem and appears as a necessary complement for a better understanding of a chemical structure.

String Model of Chemical Reactions, chemical reaction system A composed of several molecules, and the perturbation effects to it. Relativistic corrections including spin-dependent interactions or external electromagnetic fields including solvent effects are here treated as perturbations.

A Phase Space Essay,ics, i.e. quantum mechanics before Heisenberg and Schrödinger, was essentially formulated in phase space. But with the advent of modern quantum mechanics, emphasis was put on Hilbert space instead, and phase space became a dangerous place to rest in because of the uncertainty relation between position and momentum.
