Abstract

A confined, non-relativistic, 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 non-relativistic 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.

摘要

一个受限的、非相对论性的、加速运动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，关注有限的总行进距离将简单理论分析的优势与桌面实验的前景结合起来。我们展示了一个沿着渐近静态世界线加速运动的电荷，其具有固定的传输距离和非相对论性最大速度，发射出自洽的解析功率、光谱和能量。经典辐射呈普朗克分布，并伴有一个相关的加速温度。这是第一条完全参数化、光谱求解、有限距离的世界线。
