Encouraged by recent advances in revealing significant effects of van der Waals wells on reaction dynamics, many people assume that van der Waals wells are inevitable in chemical reactions. Here we find that the weak long-range forces cause van der Waals saddles in the prototypical C(1D)+D2 complex-forming reaction that have very different dynamical effects from van der Waals wells at low colli...

An atomic force microscope (AFM) was used to measure the interactions between a flat Teflon AFTM surface and an -alumina or amorphous silica sphere in cyclohexane as a function of distance of separation. Repulsive van der Waals (vdW) forces were predicted for the interactions between Teflon AFTM and -alumina or amorphous silica according to the negative Hamaker constants, which were calculated ...

We study the van der Waals (vdW) interaction between a polarizable particle and grounded conducting corrugated surface. For sinusoidal corrugations, one knows that, under action of lateral vdW force, an isotropic is always attracted to nearest corrugation peak, with such behavior called in present paper as peak regime. Here, considering anisotropic particle, making analytical calculations valid...

All bodies are surrounded by a fluctuating electromagnetic field due to thermal and quantum fluctuations of the current density inside the bodies. This fluctuating field is responsible for many important phenomena such as the radiative heat transfer, the van der Waals interaction and the van der Waals friction between bodies. In contrast to the van der Waals interaction, for which theory is wel...

A “best-of-both-worlds” van der Waals (vdW) density functional is constructed, seamlessly supplementing the strongly constrained and appropriately normed (SCAN) meta-generalized gradient approximation for shortand intermediate-range interactions with the long-range vdW interaction from rVV10, the revised Vydrov–van Voorhis nonlocal correlation functional. The resultant SCANþrVV10 is the only vd...

We propose the nano-scale displacement sensor with high resolution for weak-force systems could be realized based on vertical stacked two-dimensional (2D) atomic corrugated layer materials bound through Van der Waals (VdW) interaction. Using first-principles calculations, we found the electronic structure of bi-layer blue phosphorus (BLBP) varies appreciably to both the lateral and vertical int...

Abstract For Anti-de Sitte (AdS) black holes, the isochoric heat capacity of system is vanished, while isobaric not. However, this situation does not hold on for de Sitter (dS) holes. In work, by introducing interaction between hole horizon and cosmological Reissner–Nordström-de (RNdS) spacetime with quintessence, we discuss phase transition system. The results show that only has similar behavi...

In this paper, we study the dynamical behavior of a microcantilever-sample system that forms the basis for the operation of atomic force microscopes (AFM). We model the microcantilever by a single mode approximation and the interaction between the sample and cantilever by a van der Waals (vdW) potential. The cantilever is vibrated by a sinusoidal input, and its de#ection is detected optically. ...

We investigate the effect of monopolar charge disorder on the classical fluctuation-induced interactions between randomly charged net-neutral dielectric slabs and discuss various generalizations of recent results [A. Naji et al., Phys. Rev. Lett. 104, 060601 (2010)] to highly inhomogeneous dielectric systems with and without statistical disorder correlations. We shall focus on the specific case...
