标题： Tantum Gravity

摘要： 我们论证了引力的一个有趣的三重缩放极限，即当普朗克常数趋于无穷大时，牛顿常数和光速趋于零，同时保持引力耦合常数 $G_N\,c^{-4}$ 和组合 $\hbar\,c$ 固定不变。我们将这一极限理论称为“tantum引力”，并在本文中描述了它的主要性质及其在物理学中的前景。 最值得注意的是，黑洞热力学定律在这种极限下仍然成立，这意味着与黑洞及其蒸发相关的难题可能在 tantum 引力中比在完整的量子引力中更容易解决。 显示英文摘要

摘要： We argue there is an interesting triple-scaling limit of quantum gravity, namely when Planck's constant scales to infinity while Newton's constant and the speed of light tend to zero, keeping fixed the gravitational coupling $G_N\,c^{-4}$ and the combination $\hbar\,c$. We refer to this limiting theory as ``tantum gravity'' and describe in this Letter some of its main properties and prospects for physics. Most notably, the laws of black hole thermodynamics survive this limit, which means that puzzles related to black holes and their evaporation could be addressed more easily in tantum gravity than in fully-fledged quantum gravity.
