We show that there exist scalar field theories with plausible one-particle states in general $D$ dimensional nonstationary curved spacetimes whose propagating modes are localized on $d\le D$ dimensional hypersurfaces, and the corresponding stress tensor resembles the bare cosmological constant $\lambda_B$ in the $D$ dimensional bulk. We show that nontrivial $d=1$ dimensional solutions correspond to $\lambda_B 2$ we obtain $O(d-1,1)$, $O(d-1)\times {\rm Diff}(\mathbb{R}^1)$ and $O(d-1,1)\times O(d-2)\times {\rm Diff}(\mathbb{R}^1)$ corresponding to, respectively, $\lambda_B 0$.

裸宇宙常数的量子

我们表明，在一般 $D$ 维非平稳弯曲时空中存在具有似是而非的单粒子状态的标量场理论，其传播模式位于 $d\le D$ 维超曲面上，并且相应的应力张量类似于裸宇宙学常数 $\ $D$ 维度块中的 lambda_B$。我们证明非平凡的 $d=1$ 维解对应于 $\lambda_B 2$ 我们得到 $O(d-1,1)$, $O(d-1)\times {\rm Diff}(\mathbb{R }^1)$ 和 $O(d-1,1)\times O(d-2)\times {\rm Diff}(\mathbb{R}^1)$ 分别对应于 $\lambda_B 0$ .
