A new light on the darkest corner of the landscape

Blåbäck, Johan, Danielsson, Ulf, Dibitetto, Giuseppe

Understand

Motivated by the recently proposed bounds on the slow-roll parameters for scalar potentials arising from string/M-theory compactifications, a.k.a.

the Refined de Sitter Swampland conjecture, we explore the sharpness of such constraints within 4D supergravities coming from compactifications of massive type IIA string theory on $\mathbb{T}^{6}/(\mathbb{Z}_{2}\,\times\,\mathbb{Z}_{2})$.
With the aid of a numerical technique, known as differential evolution, we are able to find a de Sitter extremum which is fully metastable up to one single flat direction.
This solution is supported by spacetime filling sources such as O6 planes and KK monopoles.
