A Guarino, E Malek, H Samtleben - Physical Review Letters, 2021 - APS
Stable nonsupersymmetric anti–de Sitter (AdS) vacua of string theory are widely believed
not to exist. In this Letter, we analytically compute the full bosonic Kaluza-Klein spectrum …

Negative scalar potentials and the swampland: an Anti-Trans-Planckian Censorship Conjecture
