论文摘要
对于黑体辐射中小极化粒子的动量扩散常数的一般表达是一种普遍的表达，并显示与在热环境中这种粒子的长波长碰撞分解率密切相关。我们展示了这种扩散常数如何出现在黑体辐射引起的两个偶极子的稳态光子发射速率中。此外，我们考虑了在黑体田中移动的小极化粒子上的爱因斯坦 - hopf阻力，并从洛伦兹的力量转化中得出了完全相对论的形式。
A general expression is derived for the momentum diffusion constant of a small polarizable particle in blackbody radiation, and is shown to be closely related to the long-wavelength collisional decoherence rate for such a particle in a thermal environment. We show how this diffusion constant appears in the steady-state photon emission rate of two dipoles induced by blackbody radiation. We consider in addition the Einstein--Hopf drag force on a small polarizable particle moving in a blackbody field, and derive its fully relativistic form from the Lorentz transformation of forces.
