The momentum transfer from an electromagnetic field to reflecting and absorbing surfaces was asserted by the Maxwell equations. This phenomenon, with important implications for the development of the cosmos, has also been investigated in the discretized energy scale using optomechanical devices. With the quantization of the electromagnetic field, it was discovered that the vacuum field may influence the dynamics of some physical systems, such as in the Casimir effect and the radiative decay of an atom. Here, the effect of the radiation pressure by the electromagnetic vacuum on the surface of a compressible conductor is analyzed, and the model based on the Born-Markov master equation predicts a harmonic strain and momentum analog to the classical counterpart. A fundamental difference observed is the oscillating purity of the deformation state. In addition, it was demonstrated that the time-averaged force originated from the elastic reflection of the vacuum-field modes is comparable to the Casimir force for two ideal metallic plates separated by a distance proportional to the reflectivity cutoff wavelength.

导体对真空场辐射压力的弹性响应

麦克斯韦方程确定了从电磁场到反射和吸收表面的动量传递。这种现象对于宇宙的发展具有重要意义,也已经使用光机械装置在离散的能量尺度上进行了研究。通过电磁场的量化,发现真空场可能会影响某些物理系统的动力学,例如卡西米尔效应和原子的辐射衰减。在此,分析了电磁真空对可压缩导体表面的辐射压力的影响,并且基于Born-Markov主方程的模型预测了与经典对应物类似的谐波应变和动量。观察到的基本差异是变形状态的振荡纯度。
