On de Sitter vacua in O(d,d) invariant cosmology
Yang Liu, Antonio Padilla, Paul M. Saffin +1
We perform a thorough analysis of de Sitter vacua in O(d,d) invariant cosmologies. Starting with a homogeneous and isotropic framework we examine conditions for the existence of su…

The cosmological constant and the weak gravity conjecture
Yang Liu, Antonio Padilla, Francisco G. Pedro
We examine the descent via membrane nucleation through a landscape of vacua where the cosmological constant is given by a combination of four-form fluxes. It has been shown that th…
