What is the deferences between Exchange and correlation and also what is Exchange-correlation hole?
 
Physics news on Phys.org
In fact I want to know that whether sum of the charges of exchange hole and correlation hole is +e (e:electron charge) or each of them has the charge +e so that some of their charges is +2e?
 

Thread 'Instantaneous dipole moment and orbitals'

Hi. I have got question as in title. How can idea of instantaneous dipole moment for atoms like, for example hydrogen be consistent with idea of orbitals? At my level of knowledge London dispersion forces are derived taking into account Bohr model of atom. But we know today that this model is not correct. If it would be correct I understand that at each time electron is at some point at radius at some angle and there is dipole moment at this time from nucleus to electron at orbit. But how...
