The DNA of Calabi–Yau Hypersurfaces

open access: yesFortschritte der Physik, EarlyView.
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.

On the β$$ \beta $$‐effect in the baroclinic instability of a continuously stratified atmosphere

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We solve the quasi‐geostrophic equation numerically to analyze baroclinic instability in a continuously stratified atmosphere. On the β$$ \beta $$‐plane, deviations from classical models alter instability growth rates and modal structures, leading to the emergence of unstable lobes and a stable region at very large wavelengths.

Entanglement in Quantum Systems Based on Directed Graphs

open access: yesAdvanced Quantum Technologies, EarlyView.
The entanglement properties of quantum states associated with directed graphs are investigated. It is proved that the vertex degree distribution fully determines this entanglement measure, which remains invariant under vertex relabeling, thereby highlighting its topological character.

Noise Suppression in Organic Photodiodes: A Comprehensive Review of Mechanistic Insights and Design Principles

open access: yesSmall, EarlyView.
Organic photodiodes are limited by dark current and excess low‐frequency noise. This review synthesizes mechanisms of noise, links to three leakage pathways, and unifies measurement practice with device design. By outlining energetics, morphology, and interface strategies, it provides validated routes to lower noise floors and higher detectivity across
