摘要:
一个受约束、缓慢运动且加速的电子被证明会发射热辐射。由于实验室在处理直线运动时面临空间限制,关注有限的总行程距离结合了简单理论分析的优点与桌面实验的前景。我们证明了一个沿渐近静态世界线运动的加速电荷,具有固定的行程距离和缓慢的最大速度,能够发射自洽的解析功率、谱和能量。经典辐射呈普朗克分布,并具有相应的加速温度。这是第一个完全参数化、谱已求解的有限距离世界线。
英文摘要:
A confined, slow-moving, accelerating electron is shown to emit thermal radiation. Since laboratories face spatial constraints when dealing with rectilinear motion, focusing on a finite total travel distance combines the benefits of simple theoretical analysis with prospects for table-top experimentation. We demonstrate an accelerated moving charge along an asymptotically static worldline with fixed transit distance and slow maximum speed, emitting self-consistent analytic power, spectra, and energy. The classical radiation is Planck distributed with an associated acceleration temperature. This is the first fully parametrized, spectrum-solved, finite-distance worldline.
