This feature should be preserved by any approximation when determining the energy. This is not the case when a configuration-interaction expansion like (4.1.1) i

An example is the binding energy of atoms in molecules, to which correlations contribute considerably. They should therefore be considered an important ingredient of chemical bonding.

MOSFET High-Voltage Technologies,at most experiments in semiconductor physics can be described within a one-particle picture. It merely shows that the quasiparticle concept works very well in these systems. A noticeable exception is the fractional quantum Hall effect, which is based exclusively on correlations and in which the quas
