相对论时空结构的普朗克黑体谱
The Planck Blackbody Spectrum Follows from the Structure of Relativistic Spacetime
摘要：
在这里，我们表明，在经典物理学中，普朗克黑体光谱可以直接从相对论时空的结构。在非惯性系中，正温度下的热辐射与零点辐射直接相关，零点辐射的频谱遵循时空的测地线结构。在非惯性系中，零点辐射与正温度下的热辐射之间的联系是通过时间膨胀保角变换实现的。将该谱移回Minskowski时空，得到普朗克谱。
英文摘要：
Here we show that within classical physics, the Planck blackbody spectrum can be derived directly from the structure of relativistic spacetime. In noninertial frames, thermal radiation at positive temperature is connected directly to zero-point radiation whose spectrum follows from the geodesic structure of the spacetime. The connection between zero-point radiation and thermal radiation at postive temperature is through a time-dilating conformal transformation in the noninertial frame. Transferring the spectrum back to Minskowski spacetime, the Planck spectrum is obtained.
