我们开发了一个统一的散射方法来动态卡西米尔问题，可应用于加速边界，以及色散的相对运动的对象。导出了加速边界辐射的一般（迹）公式。提供了用于具有各种尺寸的不同形状并且经历旋转或线性运动的物体的应用。在此框架内，光子产生的背景下，讨论了调制的光学反射镜。对于色散对象，我们发现一般结果仅在散射矩阵。具体地说，我们讨论了旋转物体上的真空摩擦，以及原子平行于表面运动时的摩擦。
We develop a unified scattering approach to dynamical Casimir problems which can be applied to both accelerating boundaries, as well as dispersive objects in relative motion. A general (trace) formula is derived for the radiation from accelerating boundaries. Applications are provided for objects with different shapes in various dimensions, and undergoing rotational or linear motion. Within this framework, photon generation is discussed in the context of a modulated optical mirror. For dispersive objects, we find general results solely in terms of the scattering matrix. Specifically, we discuss the vacuum friction on a rotating object, and the friction on an atom moving parallel to a surface.
