真空对加速运动的反作用对惯性质量的贡献

Contribution to inertial mass by reaction of the vacuum to accelerated motion

Alfonso Rueda, Bernhard Haisch

摘要:

我们提出了一种方法的起源惯性涉及的电磁分量的量子真空,并提出这作为一种替代马赫的原则。从惯性观测者的角度看,对撞击在加速物体上的经典零点辐射的动量通量的初步分析表明,惯性对加速的阻力可能至少部分是源于真空的反作用力。这种分析避免了先前用于导出类似结果的粒子场相互作用动力学的特设建模。本方法不依赖于在粒子点发生的情况,而是依赖于外部观察者如何评估撞击在加速物体上的零点辐射的运动学特性。本文的分析得到了相对论形式的运动方程。它的协变形式产生一个简单的结果,可以解释为对惯性质量的贡献。我们的方法是相关的等效原理萨哈罗夫的猜想之间的联系爱因斯坦行动和真空。提出的论点因此可以被解释为萨哈罗夫猜想的后代,我们试图将赋予质量的性质归因于真空的电磁分量-可能还有其他分量。在这种观点中,物体的物理动量与瞬时包含在物体特征固有体积中的真空的辐射动量通量有关。被加速的物体和真空之间的相互作用过程(类似于电磁辐射的吸收或散射)似乎会产生一种对加速的物理阻力(反作用力),这在历史上被称为惯性。

英文摘要:

We present an approach to the origin of inertia involving the electromagnetic component of the quantum vacuum and propose this as an alternative to Mach's principle. Preliminary analysis of the momentum flux of the classical zero-point radiation impinging on accelerated objects as viewed by an inertial observer suggests that the resistance to acceleration attributed to inertia may be at least in part a force of opposition originating in the vacuum. This analysis avoids the ad hoc modeling of particle-field interaction dynamics used previously to derive a similar result. This present approach is not dependent upon what happens at the particle point, but on how an external observer assesses the kinematical characteristics of the zero-point radiation impinging on the accelerated object. A relativistic form of the equation of motion results from the present analysis. Its covariant form yields a simple result that may be interpreted as a contribution to inertial mass. Our approach is related by the principle of equivalence to Sakharov's conjecture of a connection between Einstein action and the vacuum. The argument presented may thus be construed as a descendant of Sakharov's conjecture by which we attempt to attribute a mass-giving property to the electromagnetic component -- and possibly other components-- of the vacuum. In this view the physical momentum of an object is related to the radiative momentum flux of the vacuum instantaneously contained in the characteristic proper volume of the object. The interaction process between the accelerated object and the vacuum (akin to absorption or scattering of electromagnetic radiation) appears to generate a physical resistance (reaction force) to acceleration suggestive of what has been historically known as inertia.
