Non-singular string cosmology via corrections
Peng Wang, Houwen Wu, Haitang Yang +1
In string theory, an important challenge is to show if the big-bang singularity could be resolved by the higher derivative corrections. In this work, based on the Hohm-Zwiebac…
Construct corrected or loop corrected solutions without curvature singularities
Peng Wang, Houwen Wu, Haitang Yang +1
For the bosonic gravi-dilaton system, we provide systematical approaches to construct non-perturbative string cosmological solutions without curvature singularities, which can matc…
Strong Cosmic Censorship for a Scalar Field in a Born-Infeld-de Sitter Black Hole
Qingyu Gan, Guangzhou Guo, Peng Wang +1
It has been shown that the Strong Cosmic Censorship (SCC) can be violated by a scalar field in a near-extremal Reissner-Nordstrom-de Sitter black hole. In this paper, we investigat…
Are nonperturbative AdS vacua possible in bosonic string theory?
Peng Wang, Houwen Wu, Haitang Yang
In this paper, following the work of Hohm and Zwiebach [arXiv:1905.06583], we show that in bosonic string theory nonperturbative anti-de Sitter (AdS) vacua could exist with all $α^…
