The London model of Van-der-Waals forces: what's next?

London's polarization model is extended over a wide range of VdW attraction. At low temperature the VdW attraction is the main competitor to the Casimir force. As the temperature is raised, the VdW force decreases by virtue of the polsrizability falling down gradually. This trend is advanced in multilevel systems. such as the off-center defects, where the polarizability is renormalized through electron-vibrational mode coupling to gain a multiple vibronic enhancement by many orders of magnitude. Applications to high-Tc superconductivity and cosmology are conceivable.
