非相对论性量子引力

Aspects of nonrelativistic quantum gravity

Johan Hansson

摘要:

研究了量子引力的非相对论方法。至少对弱引力场来说,它应该是一个有效的近似。这种方法可以用来指出更精确的量子引力理论所固有的问题和前景,而这些问题和前景还有待发现。非相对论性量子引力,例如,显示出完全禁止黑洞的希望(这将消除奇异性,也解决了黑洞信息悖论),甚至在球对称的情况下也给出了引力辐射,并支持非定域性(量子纠缠)。它的预测也应该在远高于“普朗克尺度”的长度尺度上通过现有技术可行的高精度实验进行测试。

英文摘要:

A nonrelativistic approach to quantum gravity is studied. At least for weak gravitational fields it should be a valid approximation. Such an approach can be used to point out problems and prospects inherent in a more exact theory of quantum gravity, yet to be discovered. Nonrelativistic quantum gravity, e.g., shows promise for prohibiting black holes altogether (which would eliminate singularities and also solve the black hole information paradox), gives gravitational radiation even in the spherically symmetric case, and supports non-locality (quantum entanglement). Its predictions should also be testable at length scales well above the "Planck scale", by high-precision experiments feasible with existing technology.
