Abstract: (APS)
In recent times, a considerable effort has been dedicated to identify certain conditions—the so-called swampland conjectures—with an eye on identifying effective theories which have no consistent UV-completions in string theory. In this paper, we examine the anti–de Sitter vacua corresponding to solutions which arise from purely nonperturbative contributions to the superpotential and show that these solutions satisfy the (axionic) weak gravity conjecture and the AdS-moduli scale separation conjecture, without particular fine-tuning of the parameters. We also sketch out their advantages over other constructions.
