标题： A toy model of quantum gravity with a quantized cosmological constant

摘要： 氢原子的路径积分，例如，被表述为一种一维量子引力与代表电子坐标的物质场的耦合。 （重整化的）宇宙学常数，对应于能量本征值，在此模型中因此被量子化。 对量子化宇宙学常数的可能含义进行了简要讨论。 显示英文摘要

摘要： The path integral for the hydrogen atom, for example, is formulated as a one-dimensional quantum gravity coupled to matter fields representing the electron coordinates. The (renormalized) cosmological constant, which corresponds to the energy eigenvalue, is thus quantized in this model. Possible implications of the quantized cosmological constant are briefly discussed.
