We study de Sitter configurations in ten-dimensional string models where supersymmetry is either absent or broken at the string scale. To this end, we derive expressions for the cosmological constant in general warped flux compactifications with localized sources, which yield no-go theorems that extend previous works on supersymmetric cases. We frame our results within a dimensional reduction and connect them to a number of Swampland conjectures, corroborating them further in the absence of supersymmetry. Furthermore, we construct a top-down string embedding of de Sitter brane-world cosmologies within unstable anti-de Sitter landscapes, providing a concrete realization of a recently revisited proposal.

Non-supersymmetric heterotic strings on $AdS_{4}\times S^{3}\times S^{3}$
Non-supersymmetric heterotic string compactifications on AdS4 x S3 x S3 with two fluxes develop tachyonic instabilities when fluxes are close in magnitude and show inverse scale separation when far apart, but brane nu...

Non-supersymmetric strings on AdS$_3$: a world-sheet perspective
On AdS3×S3×S3×S1, a Wilson-line deformation of the Spin(16)×Spin(16)⋊Z2 heterotic string produces a level-matched tachyon, so the classical moduli space contains unstable regions.

Non-supersymmetric branes and discrete topological terms
A direct computation from the tentative NS5-brane spectrum gives the opposite Z3 topological term (1/3 vs 2/3) from Tachikawa-Zhang, so the spectrum or the inflow interpretation must change.

Dark bubble cosmology and the equivalence principle
In dark bubble cosmology, non-abelian gauge fields like gluons would couple to induced gravity with the wrong sign, making the proton's gravitational mass about 1% of its inertial mass and ruling out the scenario agai...
