Charting the landscape of $ \mathcal{N} = 4 $ flux compactifications [PDF]

, 2011
We analyse the vacuum structure of isotropic Z2 × Z2 flux compactifications, allowing for a single set of sources. Combining algebraic geometry with supergravity techniques, we are able to classify all vacua for both type IIA and IIB backgrounds with ...

Moduli identification methods in Type II compactifications

Journal of High Energy Physics, 2018
Recent work on four dimensional effective descriptions of the heterotic string has identified the moduli of such systems as being given by kernels of maps between ordinary Dolbeault cohomology groups.

The Legendrian Hopf link has exactly two Lagrangian fillings

Journal of Topology, Volume 19, Issue 4, December 2026.
Abstract We prove that there are precisely two embedded exact Lagrangian fillings of the standard Legendrian Hopf link, up to compactly supported Hamiltonian isotopy. It was known that the standard Legendrian Hopf link admitted at least two such Lagrangian fillings: we show these are all.

Phospholipid Monolayers and Vesicular Membranes Show Only Minor Structural Changes After Interaction With α$\alpha$‐Synuclein at Low and Physiological Concentrations

ChemPhysChem, Volume 27, Issue 20, 28 October 2026.
The interaction of α$\alpha$‐synuclein with lipid membranes in the synapse is intensively discussed in view of pathologies of neurodegeneration. By X‐ray diffraction from monolayer, lipid vesicles, and synaptic vesicles at different α$\alpha$‐synuclein concentrations, structural changes of the membrane can be probed in response to the interaction.

Sharpening the boundaries between flux landscape and swampland by tadpole charge

Journal of High Energy Physics, 2021
We investigate the vacuum structure of four-dimensional effective theory arising from Type IIB flux compactifications on a mirror of the rigid Calabi-Yau threefold, corresponding to a T-dual of the DeWolfe-Giryavets-Kachru-Taylor model in Type IIA flux ...

Warped flux compactification and brane gravity [PDF]

Journal of Cosmology and Astroparticle Physics, 2005
We find a simple exact solution of 6-dimensional braneworld which captures some essential features of warped flux compactification, including a warped geometry, compactification, a magnetic flux, and one or two 3-brane(s). In this setup we analyze how the Hubble expansion rate on each brane changes when the brane tension changes.

Energy‐Dependent Nucleation and Hierarchical Aggregation of Gold Nanoparticles During Synchrotron X‐Ray Radiolysis Revealed by in Situ Transmission Imaging and SAXS

Nano Select, Volume 7, Issue 10, October 2026.
In situ x‐ray transmission imaging and monochromatic small angle x‐ray scattering (SAXS) measurements of Au precursor solution establish that precise tuning of incident photon energy controls not only the radiolytic yield but the entire hierarchical aggregation trajectory, offering a sophisticated blueprint for the rational design of functional ...

Non‐Geometric T‐Duality as Higher Groupoid Bundles With Connections

Fortschritte der Physik, Volume 74, Issue 10, October 2026.
This paper describes T‐duality between geometric and non‐geometric backgrounds using spans of higher groupoid bundles with adjusted connections. This framework incorporates explicit metric formulas, scalar fields, and Q$Q$‐fluxes. The resulting model reproduces key literature examples while maintaining covariance under the full T‐duality group O(n,n;Z)$

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.
