标题： Quantum Vacuum Self-Propulsion and Torque

摘要： 本文综述了我们最近为理解自发的量子真空力和力矩所做的努力，这些力和力矩要求一个静止物体与黑体背景辐射处于非热平衡状态。 我们通过电极化率的幂次展开来进行系统研究。 在一阶情况下，不会出现自发力，尽管可能出现力矩，但前提是该物体由非互易材料组成。 在二阶情况下，无论是普通材料还是力矩都可以出现，但前提是该物体是不均匀的。 在更高阶的情况下，这个最后的要求可以被移除。 我们给出了一些展示二阶自发力和力矩的物体例子，其中一些可能可以通过观测来验证。 显示英文摘要

摘要： This article summarizes our recent efforts to understand spontaneous quantum vacuum forces and torques, which require that a stationary object be out of thermal equilibrium with the blackbody background radiation. We proceed by a systematic expansion in powers of the electric susceptibility. In first order, no spontaneous force can arise, although a torque can appear, but only if the body is composed of nonreciprocal material. In second order, both forces and torques can appear, with ordinary materials, but only if the body is inhomogeneous. In higher orders, this last requirement may be removed. We give a number of examples of bodies displaying second-order spontaneous forces and torques, some of which might be amenable to observation.
