Einstein described the damping and thermalization of the center-of-mass motion of a mirror placed inside a blackbody cavity by collisions with thermal photons. While the time for damping even a microscale or nanoscale object is so long that it is not experimentally viable, we show that this damping is feasible using the high-intensity light from an amplified thermal light source with a well-defined chemical potential. We predict this damping of the center-of-mass motion will occur on timescales of tens of seconds for small optomechanical systems.

实现爱因斯坦的镜子：用热光子气体进行光机阻尼

爱因斯坦描述了通过与热光子碰撞放置在黑体腔内的镜子的质心运动的阻尼和热化。虽然对微米级或纳米级物体进行阻尼的时间太长，以至于在实验上不可行，但我们表明，使用来自具有明确定义的化学势的放大热光源的高强度光，这种阻尼是可行的。我们预测，对于小型光机械系统，质心运动的这种阻尼将在数十秒的时间尺度上发生。
