论文摘要
有效的真空能量密度由非平凡扭曲分布贡献，而裸真能量密度可以看作是辅助典型典型场电位的能量密度。我们发现，负裸真能密度来自弦界的裸露能量密度会导致单调降低的典型潜力，而从Swampland的正质量则导致元素稳定或稳定的de Sitter，就像电势一样。此外，在后一种情况下，必须使用非平凡的Brans-Dicke，例如典型场和引力场之间的耦合。
The effective vacuum energy density contributed by the non-trivial contortion distribution and the bare vacuum energy density can be viewed as the energy density of the auxiliary quintessence field potential. We find that the negative bare vacuum energy density from string landscape leads to a monotonically decreasing quintessence potential while the positive one from swampland leads to the meta stable or stable de Sitter like potential. Moreover, the non-trivial Brans-Dicke like coupling between quintessence field and gravitation field is necessary in the latter case.
