The original project was aimed towards developing a comprehensive theory of dispersion forces on the basis of macroscopic quantum electrodynamics. Important aspects to be included were microscopic precision, complex geometries and materials, continuous media, non-trivial atomic and field states and moving bodies. The findings of this project together with recent successes in the field of topological materials have led to a focus on dispersion forces which do not act in the normal direction with respect to the surface of the interacting objects.To account for these developments, this continuation project is aimed at developing a theory of non-normal dispersion forces. These includeA. Lateral dispersion forces and dispersion torques andB. Dissipative dispersion forces such as quantum friction and quantum frictional torques.The continuation project is intimately related to the original project by building on its results with respect to complex materials, non-trivial atomic states and moving objects. It holds the promise to enable an experimental detection of quantum friction and Casimir torques for the first time and opens the perspective of new optomechanical actuation schemes.

最初的项目旨在建立一个基于宏观量子电动力学的色散力的综合理论。重要的方面包括微观精度、复杂的几何和材料、连续介质、非平凡的原子和场态以及运动的物体。这个项目的发现以及最近在拓扑材料领域的成功导致了对色散力的关注，色散力在相互作用的物体表面上不按正常方向作用。为了解释这些发展，这个继续项目的目的是发展一种非正态色散力的理论。这些include。横向色散力和色散力矩。耗散色散力，如量子摩擦和量子摩擦力矩。延续项目与原始项目密切相关，建立在复杂材料、非平凡原子状态和运动物体的基础上。它有望首次实现量子摩擦和卡西米尔扭矩的实验检测，并为新的光机械驱动方案开辟了前景。
