论文摘要

在对分散力的研究中,及其独特的缩放定律的未粘贴,智障和热渐近线被认为是基石结果,该结果控制了不同分离的相互作用。在这里,我们表明,当粒子在培养基中相互作用时,延迟的影响在质上有所不同,因此有必要全面考虑非单调电位。我们讨论了多种情况的不同制度,并发现迟发渐近线的异常行为。它可以更改标志,并导致陷阱潜力。

In the study of dispersion forces, nonretarded, retarded and thermal asymptotes with their distinct scaling laws are regarded as cornerstone results governing interactions at different separations. Here, we show that when particles interact in a medium, the influence of retardation is qualitatively different, making it necessary to consider the non-monotonous potential in full. We discuss different regimes for several cases and find an anomalous behaviour of the retarded asymptote. It can change sign, and lead to a trapping potential.
