abstract

The higher-derivative $\alpha'$ corrections consistent with $O(d,d)$ duality invariance can be completely classified for cosmological, purely time-dependent backgrounds. This result is used to show that there are duality invariant theories featuring string-frame de Sitter vacua as solutions that are non-perturbative in $\alpha'$, thus suggesting that classical string theory may realize de Sitter solutions in an unexpected fashion.

  1. Non-singular string cosmology via $\alpha^{\prime}$ corrections

    hep-th 2019-09 reject novelty 6.0 of 10

    The paper builds non-singular bouncing FLRW solutions in the O(d,d) invariant string cosmology action, but the higher-order coefficients are free inputs and the action consistency is unverified.
