Mass spectrum of type IIB flux compactifications — comments on AdS vacua and conformal dimensions

open access: yesJournal of High Energy Physics, 2023
In this note we study the mass spectrum of type IIB flux compactifications. We first give a general discussion of the mass matrix for F-term vacua in four-dimensional N $$ \mathcal{N} $$ = 1 supergravity theories and then specialize to type IIB Calabi ...

Gravitoelectric effect in the condensed magnetic sea

open access: yesIET Quantum Communication, Volume 5, Issue 2, Page 185-195, June 2024.
The Soon Joe generator produced a certain amount of electricity in the dark stationary state. Gravity or gravitational wave can induce the magnetic seas because gravitons captured in the magnetic seas should induce the gravitoelectric effect without the photoelectric effects. As a result, we formulated a new law for magnetism on Earth. Abstract Trapped

dS vacua and the swampland

open access: yesJournal of High Energy Physics, 2019
In this note we revisit some of the recent 10d and 4d arguments suggesting that the uplifting of supersymmetric AdS vacua leads to a flattening of the potential, preventing the formation of dS vacua.

On scale separation in type II AdS flux vacua

open access: yesJournal of High Energy Physics, 2020
We study the separation of AdS and Kaluza-Klein (KK) scales in type II 4d AdS orientifold vacua. We first address this problem in toroidal/orbifold type IIA vacua with metric fluxes, corresponding to compactifications in twisted tori, both from the 4d ...

Octonionic Magical Supergravity, Niemeier Lattices, and Exceptional & Hilbert Modular Forms

open access: yesFortschritte der Physik, Volume 72, Issue 2, February 2024.
Abstract The quantum degeneracies of Bogomolny‐Prasad‐Sommerfield (BPS) black holes of octonionic magical supergravity in five dimensions are studied. Quantum degeneracy is defined purely number theoretically as the number of distinct states in charge space with a given set of invariant labels.

Tadpole conjecture in non-geometric backgrounds

open access: yesJournal of High Energy Physics
Calabi-Yau compactifications have typically a large number of complex structure and/or Kähler moduli that have to be stabilised in phenomenologically-relevant vacua. The former can in principle be done by fluxes in type IIB solutions.

A note on O6 intersections in AdS flux vacua

open access: yesJournal of High Energy Physics
The DGKT-CFI construction of AdS flux vacua in type IIA string theory has interesting features such as classical moduli stabilization and a parametric scale separation between the Hubble scale and the Kaluza-Klein scale.

An index for flux vacua

open access: yesJournal of High Energy Physics
We propose to use the winding number of the gradient of a scalar potential as a simple topological index that relates critical points in the interior of the scalar field space to the behavior of the potential at the (asymptotic) boundary of the field ...

A positive metric over DGKT vacua

open access: yesJournal of High Energy Physics
We study the notion of a metric over the space of AdS solution in string theory, leading to an associated distance between them. Such a distance is the idea underlying the AdS distance conjecture.

Systematics of type IIA moduli stabilisation

open access: yesJournal of High Energy Physics, 2020
We analyse the flux-induced scalar potential for type IIA orientifolds in the presence of p-form, geometric and non-geometric fluxes. Just like in the Calabi-Yau case, the potential presents a bilinear structure, with a factorised dependence on axions ...
