标题： Light induced "Mock Gravity" at the nanoscale

摘要： 长程吸引力相互作用的起源长期以来一直吸引着科学家。 Fatio-LeSage的粒子理论，早在1690年就已提出，并由Lorentz推广到电磁波，提出由于彼此的遮挡，两个吸收粒子在各向同性辐射场中会经历一种遵循类似重力的平方反比距离定律的吸引力。 后来，Spitzer和Gamow在星系形成的背景下引入了类似的“模拟重力”相互作用，但它们在宇宙学中的实际相关性从未被明确确立。 在这里，我们预测在准单色各向同性随机光场中，当光频率调谐到吸收线，使得粒子的电极化率的实部为零时，即所谓的Froehlich共振时，两个相同分子或纳米颗粒之间会存在模拟重力、平方反比距离的吸引力。 这些相互作用与尺度无关，适用于近场和远场分离距离。 显示英文摘要

摘要： The origin of long-range attractive interactions has fascinated scientist along centuries. The remarkable Fatio-LeSage's corpuscular theory, introduced as early as in 1690 and generalized to electromagnetic waves by Lorentz, proposed that, due to their mutual shadowing, two absorbing particles in an isotropic radiation field experience an attractive force which follows a gravity-like inverse square distance law. Similar "Mock Gravity" interactions were later introduced by Spitzer and Gamow in the context of Galaxy formation but their actual relevance in Cosmology has never been unambiguously established. Here we predict the existence of Mock-Gravity, inverse square distance, attractive forces between two identical molecules or nanoparticles in a quasi monochromatic isotropic random light field, whenever the light frequency is tuned to an absorption line such that the real part of the particle's electric polarizability is zero, i.e. at the so-called Froehlich resonance. These interactions are scale independent, holding for both near and far-field separation distances.
