Description |
Some possible approaches to the dark energy in string theory are presented. I will mainly focus on models in which potentials for the dark energy are essentially derived by classical objects. The minimal ingredients for the cosmological constant are specified potentially in IIA/IIB. On the other hand, the time-varying dark energy can be realized by an axion with weakly broken shift-symmetry, even in the presence of high-scale moduli stabilization and SUSY breaking. |
