SUSY phenomenology of KKLT flux compactifications [PDF]
Journal of High Energy Physics, 2005 We study SUSY phenomenology of the KKLT (Kachru-Kallosh-Linde-Trivedi) scenario of string theory compactifications with fluxes. This setup leads to a specific pattern of soft masses and distinct phenomenological properties. In particular, it avoids the cosmological gravitino/moduli problems.

Four-dimensional de Sitter space is a Glauber-Sudarshan state in string theory
Journal of High Energy Physics, 2021 We show that four-dimensional de Sitter space is a Glauber-Sudarshan state, i.e. a coherent state, over a supersymmetric solitonic background in full string theory. We argue that such a state is only realized in the presence of temporally varying degrees

de Sitter vacua from nonperturbative flux compactifications [PDF]
, 2013 In this work we present stable de Sitter solutions of =1 supergravity in a geometric type IIB duality frame with the addition of non-perturbative contributions.

Small Structures, Volume 7, Issue 3, March 2026.Molecular dynamics and experimental analysis show that higher crystallinity in Nafion enhances molecular packing, thereby increasing effective density. A proposed model bridges experimental and molecular‐scale observations by quantitatively linking water uptake to density variations, offering a predictive framework for optimising hydration and ...

Open string wavefunctions in flux compactifications
, 2009 We consider compactifications of type I supergravity on manifolds with SU(3) structure, in the presence of RR fluxes and magnetized D9-branes, and analyze the generalized Dirac and Laplace-Beltrami operators associated to the D9-brane worldvolume fields.

The DNA of Calabi–Yau Hypersurfaces
Fortschritte der Physik, Volume 74, Issue 2, February 2026.Abstract Genetic Algorithms are implemented for triangulations of four‐dimensional reflexive polytopes, which induce Calabi–Yau threefold hypersurfaces via Batyrev's construction. These algorithms are shown to efficiently optimize physical observables such as axion decay constants or axion–photon couplings in string theory compactifications.

FTheoryTools: Advancing Computational Capabilities for F‐Theory Research
Fortschritte der Physik, Volume 74, Issue 1, January 2026.Abstract A primary goal of string phenomenology is to identify realistic four‐dimensional physics within the landscape of string theory solutions. In F‐theory, such solutions are encoded in the geometry of singular elliptic fibrations, whose study often requires particularly challenging and cumbersome computations.

Profinite direct sums with applications to profinite groups of type ΦR$\Phi _R$
Bulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.Abstract We show that the ‘profinite direct sum’ is a good notion of infinite direct sums for profinite modules, having properties similar to those of direct sums of abstract modules. For example, the profinite direct sum of projective modules is projective, and there is a Mackey's formula for profinite modules described using these sums.

Gaugino mass term for D-branes and Generalized Complex Geometry
Journal of High Energy Physics, 2020 We compute the four-dimensional gaugino mass for a Dp-brane extended in spacetime and wrapping a cycle on the internal geometry in a warped compactification with fluxes.
