引力对质能等效关系的影响

等效原理与广义相对论的合理性问题

Rationality Problems of the Principles of Equivalence and General Relativity

指出目前只证明了惯性静质量与引力静质量是等价的。我们还没有证明惯性运动质量和引力运动质量也是等价的。利用狭义相对论的动力学效应证明了惯性运动质量与引力运动质量的不等价性。此外，还可以证明广义相对论原理是站不住脚的。这其实只是人类的一种表面感觉。因此，爱因斯坦引力理论的基础存在着严重的缺陷。我们需要更新我们对时空和引力的基本概念。

Experimental Evidences Supporting the Extension of the Equivalence Principle to Electromagnetic Fields

The principle of equivalence postulating that an acceleration is indistinguishable from gravity by any experiment, is valid within families of particles having the same passive gravitational to inertial mass ratio $m_p/m_i$. Presently experimental observations indicate that we live in a universe with one single family for which $m_p/m_i=1$, but if we consider the imaginary case of a universe with several particle families having different $m_p/m_i$, the principle of equivalence would still apply to each one of them. On the basis of this generalized formulation of the equivalence principle, whi…

等效原理与经典带电粒子的引力质量和惯性质量关系

The Equivalence Principle and gravitational and inertial mass relation of classical charged particle

我们表明，局部恒定的力，以获得一个稳定的双曲线运动制度的经典带电粒子，实际上，是一个微妙的组合施加的外力和辐射反作用力。在等效原理成立的情况下，带电粒子的引力质量应略大于其惯性质量。然而，在非常强的引力场中，引力和惯性质量关系的意外行为出现了一个有趣的新特征，在宇宙的早期阶段，或者可能在大质量黑洞附近，引力场的发散引入了临界场值。这表明等效原理在这个临界场附近不应该有效，而这个临界场肯定与量子效应相关的地方相吻合。

弯曲时空与平坦时空中引力描述的等价性

Equivalence of Descriptions of Gravity In Both Curved and Flat Space-time

论文证明，只要引入适当的坐标变换，弯曲时空中描述的大地线方程就可以转化为平坦时空中的动力学方程，也就是说，爱因斯坦引力理论等建立在弯曲时空基础上的理论都可以等价地转化为平坦时空来描述。作为例子，将球对称引力场的史瓦西解变换到平坦时空中进行研究。结果表明，在所有过程和整个时空中，包括在点r=0处，不存在任何奇点。因此，在平坦时空中讨论引力问题似乎更为合理。

从微观-宏观对偶性角度对广义相对论等效原理的新解释

New Interpretation of Equivalence Principle in General Relativity from the viewpoint of Micro-Macro duality

我们对爱因斯坦广义相对论的等效原理提出了一种新的解释：在一个小的时空区域中，引力被局部消除的自由落体框架表明存在一个边界层，在该边界层之下引力不存在，而在该边界层之上，每个这样的框架内的\textit{gravity emerges as condensation effect of microscopic motions}将不同时空点的自由落体框架联系起来。在这幅图中，引力场作为不同自由落体系的介质，由于相变中的\textit{condensation effects}，在不同的热力学纯相中表现出显著的\textit{parallelism with an order parameter to specify "degenerate vacua"}。由于广义相对论的物理基础是由于[惯性$m$ ]/[引力$m$ ]的恒定性而在质点运动的普适性中找到的，因此广义相对论的“时空”概念应该只有在这种恒定性的有效范围内才有意义，这是\textit{of empirical nature}，与通常的共识相反。最后，我们评论了观测引力波的不可能性，这将使引力子和量子引力受到质疑。

旋转超流体中的涡旋是否打破了弱等效原理？

Are vortices in rotating superfluids breaking the Weak Equivalence Principle?

在旋转超流氦中，由于规范对称性破缺，涡旋的惯性质量随涡旋大小发散。因此，涡流的惯性质量远高于涡核的经典惯性质量。涡流引力质量的同等增加受到质疑。旋转超流中的涡旋可能会打破与超流真空中光速变化有关的弱等效原理，这一可能性存在争议。实验来测试这种可能性的基础上，超流氦旋涡不会下降，在一个统一的引力场的单一影响下，在相同的速度作为超流氦质量的休息。

Serious limitations of the strong equivalence principle

It is well known that an accelerated charged particle radiates away energy. However, whether an accelerated neutral composite particle radiates away energy is unclear. We study decoherent Larmor radiation from an accelerated neutral composite object. We find that the neutral object's long wavelength radiation is highly suppressed because radiation from different charges is canceled out. However, the neutral object radiates high energy or short wavelength radiation without any suppression. In that case, radiation from each particle can be treated independently, and it is called the decoherent r…

Equivalence Principle for Antiparticles and its Limitations

We investigate the particle-antiparticle symmetry of the gravitationally coupled Dirac equation, both on the basis of the gravitational central-field problem and in general curved space-time backgrounds. First, we investigate the central-field problem with the help of a Foldy-Wouthuysen transformation. This disentangles the particle from the antiparticle solutions, and leads to a "matching relation" of the inertial and the gravitational mass, which is valid for both particles as well as antiparticles. Second, we supplement this derivation by a general investigation of the behavior of the gravi…

Testing the Influence of the Gravitational Redshift on the Casimir Effect in Space

We show that the Casimir effect should be influenced by variations of the gravitational potential. This could be tested with a satellite in a highly elliptic orbit. Still significant technology development is required to achieve a relative accuracy of $<5 \times 10^{-10}$ necessary to detect the effect around Earth. That may be obtained in the future based on recent concepts for giant casimir forces. Such a space mission could evaluate both the laws of gravitation and quantum mechanics and their interaction. A dedicated mission, Gravity-Probe C, is proposed.

等效原理与Bohr-Somerfeld-Hansson牛顿引力理论是否一致

Can Equivalence Principle be consistent with the Bohr-Somerfeld-Hansson Theory of the Newtonian Gravity

在这项工作中，我们考虑的玻尔-索末菲-汉森（旧的或准经典的）量子理论的牛顿引力，即"引力原子"的一些后果。我们证明，在这种情况下（引力中心力和量子化的角动量）离心加速度成为形式理论依赖于（比例于四度）的质量的"引力电子"围绕"引力核"旋转的任何量子数（状态）。它似乎导致了相对论等效原理的矛盾突破，这与真实的实验数据相矛盾。我们证明，这种等效原理打破并没有真正出现在（准经典）量子理论，但它必须出现在一个假设的扩展的量子理论，需要一个经典的解释一样的玻尔-索末菲角动量量子化假设。在某种意义上，它类似于贝尔-阿斯派克特分析，指出量子力学的一个假设的确定性扩展，区别于通常的量子力学，可以重现实验数据，当且仅当它是非局域的（超光速的），与相对论局域性（光度）原理相矛盾。

Considerations on Gravitational Effects Stimulated by Gravitational Fields via Classical Field Theory

A mass distribution is analyzed in terms of classical gravitational field theory. Newton's law of gravitation is consistently applied on the assumption that the equivalence of energy and mass according to Einstein's theory of relativity is valid for gravitational fields as well. Different from standard approaches the gravitational field, via its associated field energy, is handled as a source of gravitation by itself. Starting from these principles a gravitational self-shielding phenomenon is derived as a common characteristic of all mass/energy distributions. Moreover, it is demonstrated that…
