标题： Quantum Gravity as Gravitized Quantum Theory

摘要： 从对真空能量问题的新理解出发，基于相空间正则化和全息界限的结合，我们认为量子引力应被理解为“引力化的量子理论”，即量子理论中状态空间的几何和拓扑是完全动态的，这类似于爱因斯坦广义相对论中时空的动态性质。 除了将真空能量问题视为量子引力问题外，我们还讨论了涉及高阶量子干涉的“确凿证据”实验，以及对时空量子统计的实验探测。 最后，我们解决了基本粒子质量的复杂模式光谱及其混合角的问题，作为将量子引力视为引力化的量子理论的另一个显著问题。 显示英文摘要

摘要： Starting from a new understanding of the vacuum energy problem based on the combination of the phase space regularization and the holographic bound, we argue that quantum gravity should be understood as gravitized quantum theory, that is, quantum theory wherein the geometry and topology of the state-space if fully dynamical, in analogy with the dynamical nature of spacetime in Einstein's general relativity. Apart from the vacuum energy problem viewed as a quantum gravity problem, we discuss the "smoking gun" experiments involving higher order quantum interference, as well as experimental probes of the statistics of spacetime quanta. Finally, we address the conundrum of the intricately patterned spectrum of masses of elementary particles as well as their mixing angles, as another telltale problem of quantum gravity viewed as gravitized quantum theory.
