[en] Philbin and Leonhardt (2009 New J. Phys. 11 033035; 2009 arXiv:0904.2148v3 [quant-ph]) recently presented a new theory of van der Waals friction. Contrary to previous theories, they claimed that there is no 'quantum friction' at zero temperature. We argue that this theory is incorrect.
[en] Some improved combination rules for two-body Van der Waals coefficients are proposed. Several weighted means of the self-interaction coefficient in the evaluation of the Van der Waals c6 coefficient are shown to yield better results than previous ones. Numerical comparison with other calculation schemes is made. (author)
[en] We summarize the theory of van der Waals (dispersion) forces, with emphasis on recent microscopic approaches that permit the prediction of forces between solids and nanostructures right down to intimate contact and binding. Some connections are pointed out between microscopic theory and macroscopic Lifshitz theory. (topical review)
[en] Casimir effects in atomic and molecular physics are closely related to van der Waals dispersion forces and are regarded as manifestations of zero-point energy. This Comment reviews developments relating to this interpretation and offers different perspectives on them
[en] Highlights: • The FPL method is applied for the first time on the BACE1-inhibitor complex. • Interaction energy is an appropriate criterion to rank affinity of BACE1 inhibitor. • The obtained results have strong correlation with experimental data (). • The computed error is relatively small (). • The van der Waals contributes ∼56% to total interaction energy. The fast pulling of ligand (FPL) method, which evaluates the relative ligand-protein binding affinity with low CPU usage and high accuracy, was applied for the first time to determine the affinity of β-secretase 1 (BACE1) and its inhibitors using steered-molecular dynamics simulations. The total non-bonded interaction energy difference is a highly appropriate criterion to predict the relative BACE1-inhibitor binding affinity with strong correlation to experimental data () and small deviation (). The van der Waals interaction and electrostatic interaction contribute 56% and 44% to the total non-bonded interaction energy between BACE1 and its inhibitors.
