Hawking-Unruh辐射作为动力学中辐射action的不可逆结果
Hawking-Unruh radiation as irreversible consequence of radiative action in dynamics
摘要：
本文证明了在非惯性系中热环境场的Hawking-Unruh热态是一种真实的现象，是非定常动力学演化的一个标志。在带电粒子的加速运动中，Larmor辐射弛豫的反冲阻尼效应导致了独特的热功率，这类似于来自加速电荷的温暖周围场的Hawking-Unruh辐射。通过考虑加速过程中球形带电粒子周围球极化真空场固有的角演化所受的力矩，计算了横向电磁场反冲动量的阻尼效应。Hawking-Unruh效应是一种普遍存在于微观、宏观和巨观系统中的退相干现象。除了详细说明电动力学的情况下，H-U弛豫的各种效果被认为是在非平稳演化。
英文摘要：
Hawking-Unruh thermal state of warm surrounding field encountered in non-inertial frames is shown to be a real phenomenon, a marker of nonstationary dynamic evolutions. In accelerated motion of a charged particle it is shown that the recoiled damping effect of Larmor radiation relaxation leads to distinctive thermal power, which is akin to that of Hawking-Unruh radiation from warm surrounding field of the accelerated charge. The damping effect from recoil-momentum of transverse electromagnetic field is worked out by considering torque imparted to the inherently existing angular evolution of spherically polarized vacuum field around the point-like charged particle in acceleration. Hawking-Unruh effects is generally noted to be a universal marker of decoherence in evolution in all scales of microscopic, macroscopic and megascopic systems. Besides detailing the case of electrodynamics, the various efficacies of H-U relaxation are considered in the nonstationary evolutions.
