“…The form of the scalar mass matrix (6) implies that this mass formula also extends to the spin-1 sector. In particular, when evaluated for the first two levels, it reproduces the masses computed in [27].…”

Stable non-supersymmetric 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 around the G2-invariant non-supersymmetric AdS4 solution of massive IIA supergravity, and show that it is perturbatively stable. We also provide evidence that six other non-supersymmetric AdS4 solutions of massive IIA supergravity are perturbatively stable. Since previous studies have indicated that these AdS vacua may also be non-perturbatively stable, our findings pose a challenge to the Swampland Conjecture.

“…A series of dualities can be performed on the E 7(7) /SU (8) coset representative corresponding to the vacua (2.1), (2.2), in order to generate a larger set of vacua with both parameters (ϕ, χ) turned on [27]. This larger family is still N = 2 (with supersymmetry ennhacement at the N = 4 point) and generically lies outside the (SL(2, R)/SO(2)) 7 submanifold of [26]. Our parameters are related to those in [27] as χ here = χ there and e −ϕ here = 1 2 (1 + ϕ 2 there ).…”

“…For this type of AdS solutions, new powerful techniques [1,2,3] based on exceptional field theory (ExFT) [4,5] have been introduced to compute the spectrum of Kaluza-Klein (KK) excitations, dual to the spectrum of operators of the corresponding CFT. These new ExFT-based KK spectral techniques have now been employed in a variety of cases [6,7,8,9,10,11].…”

A holographic duality was recently established between an N = 4 non-geometric AdS 4 solution of type IIB supergravity in the so-called S-fold class, and a threedimensional conformal field theory (CFT) defined as a limit of N = 4 super-Yang-Mills at an interface. Using gauged supergravity, the N = 2 conformal manifold (CM) of this CFT has been assessed to be two-dimensional. Here, we holographically characterise the large-N operator spectrum of the marginallydeformed CFT. We do this by, firstly, providing the algebraic structure of the complete Kaluza-Klein (KK) spectrum on the associated two-parameter family of AdS 4 solutions. And, secondly, by computing the N = 2 supermultiplet dimensions at the first few KK levels on a lattice in the CM, using new exceptional field theory techniques. Our KK analysis also allows us to establish that this N = 2 CM is globally a compact, cylindrical Riemann surface.

“…However, new machine learning technique enables us to discover larger landscape of critical points, [4,5,6,7]. Furthermore, as an application of exceptional field theory, a powerful tool of Kaluza-Klein spectroscopy for mass spectrum was developed in [8,9,10,11,12]. It is useful in checking the perturbative stability of AdS vacua by the Breitenlohner-Freedman (BF) bound, [13,14,15].…”

On a given arbitrary Sasaki-Einstein manifold, there is the Freund-Rubin solution which is supersymmetric AdS 4 solution of eleven-dimensional supergravity. There are also nonsupersymmetric solutions: the skew-whiffed Freund-Rubin, the Pope-Warner, and the Englert solutions. From particular Sasaki-Einstein manifolds of Q 1,1,1 and M 1,1,1 there are the non-supersymmetric AdS 4 solutions discovered by Cassani, Koerber and Varela. Among those, the skew-whiffed solutions and the solutions on Q 1,1,1 and M 1,1,1 are known to be perturbatively stable, i.e, masses are above the Breitenlohner-Freedman (BF) bound. In this paper, we examine a new decay channel known as the brane-jet instability. It turns out that all AdS 4 solutions we consider are brane-jet stable. Hence, the skew-whiffed solutions and the solutions on Q 1,1,1 and M 1,1,1 are both BF and brane-jet stable.
