Summary: This study proposes a combined mechanism for winding inflation and de Sitter uplifts, using the Gopakumar-Vafa invariants of Calabi-Yau threefolds. A database is created to demonstrate the existence of Calabi-Yau threefolds with the prescribed hierarchy of invariants. Redundancies in the CICY list are also identified as a side result.

Summary: We argue that a type IIB Euclidean supergravity solution belongs to a chain of AdS x S x T vacua with self-dual flux. These vacua come from the near-horizon of specific branes and have supersymmetry for odd values of dimension. For the matrix model dual, the hallmark of conformal symmetry is a vanishing free energy when the dimension is 1. The corresponding supergravity solution indeed has vanishing on-shell action and specific fluxes need to be switched on.

Summary: In this paper, we establish multiple embeddings of d = 5 minimal (un)gauged supergravity into massive Type IIA supergravity. The internal spaces and warpings of these embeddings are the same as those of N = 1 supersymmetric (Mink(5)) AdS(5) vacua, with the modification that the U(1) R-symmetry direction is fibered over the external space by the d = 5 gauge field. Additionally, the fluxes are appropriately modified. There are various types of internal spaces and thus different embeddings of d = 5 supergravity. As examples, we present new solutions dual to six-dimensional, N = (1, 0) SCFTs compactified on a constant curvature Riemann surface and a spindle. We also provide numerous massive Type IIA embeddings for rotating, asymptotically AdS(5) black hole solutions.

Summary: In this paper, we characterize negative scalar potentials, V < 0, in d-dimensional effective theories of quantum gravity through the Anti-Trans-Planckian Censorship Conjecture (ATCC) inspired by a refined version of the TCC. The ATCC is based on the fact that sub-Planckian length modes violate the validity of the effective theory in a contracting universe. In the asymptotics of field space, we find that -V'/V >= c(0) when V' >= 0. We also derive a new asymptotic condition, V''/V >= c(0)(2), and infer the existence of a scalar with mass satisfying m(2)l(2) less than or similar to -2 in anti-de Sitter solutions.

Summary: The study explores the application of Swampland criteria to low-codimension charged objects such as strings and membranes in the context of 4D effective field theories, revealing new connections among the Swampland Conjectures through the classical RG flow of these objects' couplings. By translating constraints on UV charges and tensions to constraints on axionic kinetic terms and scalar potential of the effective field theory, it uncovers relationships among the various Swampland Conjectures.

Summary: This paper studies B-brane superpotentials that depend on several closed- and open-moduli on Calabi-Yau hypersurfaces and complete intersections. By blowing up the ambient space along a curve wrapped by B-branes in a Calabi-Yau manifold, a new manifold and the period integral satisfying the GKZ-system are obtained. Using mirror symmetry to the A-model, the superpotentials and Ooguri-Vafa invariants are calculated for specific examples of several open-closed moduli in Calabi-Yau manifolds.

Summary: This text discusses the relationship between fundamental axionic strings and infinite distance limits in 4d N = 1 EFT coupled to gravity, proposes that any 4d EFT infinite distance limit can be realized as an EFT string flow, and shows that the EFT string becomes tensionless along these limits. It also suggests that the mass of the leading tower scales similarly to T-w in Planck units, and tests these proposals in various 4d N = 1 string compactifications, finding that only the values w = 1, 2, 3 are achieved.

Summary: In this study, a new inflation scenario is proposed in flux compactification, where a zero mode scalar field of extra components of the higher dimensional gauge field is identified as the inflaton. The inflaton potential is non-local and finite, protected against higher dimensional non-derivative local operators by quantum gravity corrections.

Summary: In this paper, we demonstrate the use of Exceptional Field Theory to calculate the full Kaluza-Klein spectra of 10- and 11-dimensional supergravity. This calculation involves the deformations of backgrounds of maximal gauged supergravity by scalar modes that are not part of the consistent truncation. The results are applied to compute the spectra of squashed S-7 in N = 1 and N = 0 cases, revealing a universal formula for conformal dimensions based on Casimir operators and additional quantum numbers.

Summary: The study introduces a new swampland conjecture suggesting that the limit of vanishing gravitino mass corresponds to the massless limit of an infinite tower of states, leading to the breakdown of effective field theory. This proposal is tested in models from string theory compactification to four dimensions, with a general relation identified between gravitino mass and abelian gauge coupling. The researchers discuss the phenomenological implications of their conjecture in (quasi-)de Sitter backgrounds and derive a lower bound for the gravitino mass based on the Hubble parameter.

Summary: This study investigates M-theory compactification on twisted 7-tori with G(2)-holonomy, proposing superpotentials based on octonions and Fano planes to describe various vacuum states and inflation models. The research suggests that these models can predict benchmark targets for detecting B-modes in future cosmological observations.

Summary: In this study, we use the E(8(8)) exceptional field theory to construct a consistent truncation of IIB supergravity on S-3 x S(3) x S1, resulting in a maximal 3-dimensional N = 16 gauged supergravity containing the N = (4, 4) AdS(3) vacuum. We achieve this by adding a 7-form flux to the S(1) reduction of the dyonic E7(7) truncation on S-3 x S-3 previously constructed. Our truncation Ansatz includes a range of moduli breaking some or all of the supersymmetries in addition to the N = (4, 4) vacuum.

Summary: This paper explores certain swampland criteria from the perspective of the finiteness of black hole entropy and suggests that these criteria may fundamentally result from the finiteness of quantum gravity amplitudes.

Summary: The Swampland program aims to determine the constraints that must be satisfied by an effective field theory to be consistent with a UV embedding in a quantum gravity theory. This article provides a pedagogical introduction to the most important Swampland conjectures, their connections, and their realization in string theory compactifications.
