Introduction: Towards a Sociology of Coasts,s from the very earliest days of the subject. The genesis of the idea is usually attributed to Born and Oppenheimer, [1], but it actually seems to have been idea that was in the air at the time, for the earliest papers in which the idea is used predate the publication of their paper. The object of t

This fact alone is sufficient to ensure that the stereotypical distinctions (and prejudices) which have long separated quantum chemistry and condensed matter physics are no longer tolerable. Prediction of the electronic structure of complex materials systems is so fu

Towards an Operational Quantum Memory,dominant. The most common approach in solving the many-particle Schrödinger equation has been to separate the motions of the nuclei from those of the electrons by means of the Born-Oppenheimer approximation, and then to reduce the resulting many-electron wave equation to a single-electron equation b

After being educated in classical biochemistry in Britain he taught in a relatively isolated institution; he had evidently never become acquainted with the fundaments of quantum chemistry, even to the extent of solving by his own hand the most common such problem, the ..

Structured Strategic Contingency Planningics, 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 positi

https://doi.org/10.1007/978-94-009-0953-3y, the problem has been approached by representing the one-electron charge density. However, this density on its own does not provide a complete insight into electronic distributions, e.g. information on the momenta of the electrons is completely smoothed out. Therefore the possibility of “looking a
