“…For the model without hypers, reference [58] computed that there is always a massless combination of gravitinos at the dS critical point and they hence violate FL. They also violate the recently proposed Gravitino Distance Conjecture [64,65], since these points would be at finite distance. To date, there is no proof that this will always happen since a priori one can write down gauge invariant mass terms for gravitinos in N = 2 supergravity, but so far all examples have a massless charged gravitino.…”

Demanding that charged Nariai black holes in (quasi-)de Sitter space decay without becoming super-extremal implies a lower bound on the masses of charged particles, known as the Festina Lente (FL) bound. In this paper we fix the O(1) constant in the bound and elucidate various aspects of it, as well as extensions to d > 4 and to situations with scalar potentials and dilatonic couplings. We also discuss phenomenological implications of FL including an explanation of why the Higgs potential cannot have a local minimum at the origin, thus explaining why the weak force must be broken. For constructions of meta-stable dS involving anti-brane uplift scenarios, even though the throat region is consistent with FL, the bound implies that we cannot have any light charged matter fields coming from any far away region in the compactified geometry, contrary to the fact that they are typically expected to arise in these scenarios. This strongly suggests that introduction of warped anti-branes in the throat cannot be decoupled from the bulk dynamics as is commonly assumed. Finally, we provide some evidence that in certain situations the FL bound can have implications even with gravity decoupled and illustrate this in the context of non-compact throats.

“…Another interesting problem is to investigate the similarity of black hole potentials and the scalar field flux potentials in extended supergravity. In this context, there might arise some interesting analogies between the formalism of the black hole limits considered in this paper and of the limits for supersymmetry breaking in the context of the gravitino conjecture [58,59].…”

In this paper we discuss black hole solutions parametrized by their entropy S and temperature T in gravitational effective theories. We are especially interested in the analysis of the boundary regions in the T − S diagram, i.e. large/small values of entropy and temperature, and their relation to Swampland constraints. To explore this correlation, we couple the gravitational theories to scalar fields and connect limits of thermodynamic quantities of black holes to scalar field excursions in the corresponding solutions. Whenever the scalar fields traverse an infinite field distance, the Swampland Distance Conjecture allows for a reformulation in terms of entropy-or temperature-distance. The effective theories with scalars we investigate are Einstein-Maxwell-dilaton theory as well as N = 2 supergravity in four dimensions. The relation of the latter to type II string theory compactified on Calabi-Yau 3-folds often allows for a direct identification of the corresponding light tower of states. These setups also point towards various dualities between asymptotic regions of the black hole solution. In the context of N = 2 supergravity black holes, these thermodynamic dualities have an interpretation in terms of T-and S-dualities along the internal directions and their natural action on Kaluza-Klein and winding states.

“…In the following we formulate these main findings in a general setting, and in sections 3.1 and 3.2 we discuss them in practice for two explicit examples. For closely related applications of these asymptotic Hodge theory techniques in the context of string compactifications we refer the reader to [22,[27][28][29][30][31][32][33][34][35][36][37][38][39][40][41].…”

We study the stabilization of complex structure moduli in Type IIB flux compactifications by using recent general results about the form of the superpotential and Kähler potential near the boundaries of the moduli space. In this process we show how vacua with an exponentially small vacuum superpotential can be realized systematically and understood conceptually within asymptotic Hodge theory. We distinguish two types of vacua realizing such superpotentials that differ by the mass scales of the stabilized moduli. Masses polynomially depending on the moduli arise if the superpotential contains exponential corrections whose existence is required to ensure the non-degeneracy of the moduli space metric. We use the fact that such essential corrections are controlled by asymptotic Hodge theory and have recently been constructed for all one-and two-moduli asymptotic regimes. These insights allow us to obtain new vacua near boundaries in complex structure moduli space that include Seiberg-Witten points. In these examples we find that the scale of the vacuum superpotential can be bounded from below through the exponential of the negative D3-brane tadpole.
