SUMMARY
The atomic electric dipole moment is crucial for understanding van der Waals binding in solids, as discussed in Ashcroft and Mermin's "Solid State Physics" and Chaikin and Lubensky's work. The van der Waals forces arise from fluctuating dipole interactions, which can be analyzed through perturbation theory. Specifically, the Hamiltonian for two atoms is expanded, revealing that the energy perturbation scales with 1/R^6, where R is the distance between nuclei. This analysis requires calculating matrix elements, particularly in the case of hydrogen atoms.
