“…Since m z is lighter than m w KK , just like the strongly warped case, the stabilization of the conifold modulus in the four-dimensional supergravity description can be invalid unless the light KK modes under the species cutoff just contribute to the rescaling of K zz . For the extremely weakly warped throat, the ratio (26)) and m KK /m z ∼ |z|V (19)) are similar to or larger than 1/(2π) 2 and |z| 1/3 η UV /(2π) 2 , respectively, so as well known, m z can be lighter than the KK mass scale, which is trustworthy provided |z|/Λ 3 0 is not too close to 1.…”

“…While the appearance of the KK mode signals the existence of extra dimension, the appearance of the winding mode indicates that the point particle description should be replaced by the string description.

“…When SUSY is broken by F-term, D-term, or the antibrane uplift, the universe can be in the Minkowski or the dS vacuum, as well as the AdS vacuum with smaller |Λ|. Then it may be m 3/2 rather than |Λ| that is connected to a tower of states hence the distance conjecture [16,17] (see [18] for earlier discussion and [19] for the study on the size of extra dimensions in view of m 3/2 ).…”

We investigate the connection between the distance conjecture and the uplift potential. For this purpose, we consider the concrete model, the warped deformed conifold embedded into Type IIB flux compactifications, with the uplift potential produced by D3-branes at the tip of the throat. Whereas the various mass scales associated with towers of states can be found, it turns out that the lightest tower mass scale satisfies the scaling behavior with respect to the uplift potential, which is meaningful provided the number of D3-branes is nonzero. This indicates that the effective theory becomes invalid in the vanishing limit of the uplift potential by the descent of an infinite tower of states from UV, as predicted in the distance conjecture. Since too large uplift potential is also problematic due to the runaway behavior of the moduli potential as well as the sizeable backreaction of D3-branes, the uplift potential is bounded from both above and below. In the simple model like the KKLT or the large volume scenario in which non-perturbative effect is dominatd by the single term, this bound can be rewritten as the bound on the size of the superpotential.

On the correspondence between black holes, domain walls and fluxes

We revisit and extend the correspondence between black holes, domain walls and fluxes in type IIA compactifications. We argue that these three systems can be described by the same supergravity effective action, modulo proper identifications and adjustments. Then, we apply the correspondence to investigate swampland conjectures on de Sitter and anti-de Sitter vacua, as well as on the black hole entropy. We show that, in certain cases, swampland conjectures can be motivated from properties of black hole solutions, such as positiveness of the entropy. This provides a bottom-up rationale which is complementary to the usual tests in string theory. When asking for an agreement between the anti-de Sitter and the black hole entropy distance conjectures, we are led to an extension of the correspondence which includes geometric fluxes and the associated Kaluza-Klein monopoles domain walls. Finally, we point out that the anti-de Sitter distance conjecture is naturally implemented in certain asymptotically anti-de Sitter black holes as a consequence of a constraint involving black hole charges and supergravity gauge couplings.

The species scale provides a lower bound on the shortest possible length that can be probed in gravitational effective theories. It may be defined by the size of the minimal black hole in the theory and, as such, it has recently been given an interpretation along the lines of the celebrated black hole thermodynamics. In this work, we extend this interpretation to the case of charged species. We provide working definitions of minimal black holes for the case of uncharged and charged species constituents. Then, examining the modifications in the thermodynamic properties of near-extremal charged species compared to the uncharged case, we uncover interesting implications for the cosmology of an expanding universe, particularly within the context of the Dark Dimensions Scenario. Finally, we explore possible microscopic constructions in non-supersymmetric string theories in which towers of charged near-extremal species may arise.
