经典零点辐射散射体的标度对称性
Scaling Symmetries of Scatterers of Classical Zero-Point Radiation
摘要:
经典的辐射平衡(黑体问题)的研究使用的类比。当经典带电粒子在中心势V(r)=-k/r^n中沿圆形轨道运动时,当粒子保持匀速圆周运动以抵抗圆偏振入射平面波的辐射坍缩时,标度对称性被注意到。只有在库仑势n=1,电荷e固定的情况下,才有一个唯一的标度不变的辐射谱与频率(类似于零点辐射)从稳定的散射安排获得。这些结果表明,非电磁势是不适合的经典辐射平衡的讨论。
英文摘要:
Classical radiation equilibrium (the blackbody problem) is investigated by the use of an analogy. Scaling symmetries are noted for systems of classical charged particles moving in circular orbits in central potentials V(r)=-k/r^n when the particles are held in uniform circular motion against radiative collapse by a circularly polarized incident plane wave. Only in the case of a Coulomb potential n=1 with fixed charge e is there a unique scale-invariant spectrum of radiation versus frequency (analogous to zero-point radiation) obtained from the stable scattering arrangement. These results suggest that non-electromagnetic potentials are not appropriate for discussions of classical radiation equilibrium.
