Quantum-Chemical Approach to Electron Correlations,ctron problem. Its shortcomings were discussed in Sect. 2.8, where we showed that it is the correlation hole which every electron carries along that is missing in such an approach. The correlation hole prevents electrons from coming too close to each other and reduces their mutual Coulomb repulsion.作者: PARA 時間: 2025-3-22 10:50 作者: 集中營 時間: 2025-3-22 15:36

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.作者: 母豬 時間: 2025-3-23 04:00
Semiconductors and Insulators,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作者: 墊子 時間: 2025-3-23 08:21 作者: Negotiate 時間: 2025-3-23 13:46 作者: Terminal 時間: 2025-3-23 17:23 作者: Eclampsia 時間: 2025-3-23 21:18

Quantum-Chemical Approach to Electron Correlations, The concept of the local correlation hole becomes crucial later if we are to understand why local operators prove particularly suitable for describing electron correlations (Chap. 5).
