摘要:

从拉格朗日量出发,电磁场在沿其对称轴旋转的物体的存在下被量子化。得到了响应函数和涨落耗散关系。本文用并矢格林张量导出了旋转介质体的旋转摩擦力和辐射功率的一般公式。哈密顿量的确定和可能的推广进行了讨论。作为一个例子,在某些极限情况下,得到并讨论了半无限介质平面附近球形介质的转动摩擦力和辐射功率。

英文摘要:

Starting from a Lagrangian, the electromagnetic field is quantized in the presence of a body rotating along its axis of symmetry. Response functions and fluctuation-dissipation relations are obtained. A general formula for rotational friction and power radiated by a rotating dielectric body is obtained in terms of the dyadic Green's tensor. Hamiltonian is determined and possible generalizations are discussed. As an example, the rotational friction and power radiated by a spherical dielectric in the vicinity of a semi-infinite dielectric plane is obtained and discussed in some limiting cases.
