From the Fibonacci Icosagrid to E₈ (Part I): The Fibonacci Icosagrid, an H₃ Quasicrystal

Crystals
This paper introduces a new kind of quasicrystal by Fibonacci-spacing a multigrid of a certain symmetry, like H2, H3, T3, etc. Multigrids of a certain symmetry can be used to generate quasicrystals, but multigrid vertices are not a quasicrystal due to ...

Quantum conformal gravity

Journal of High Energy Physics
Abstract We present the manifestly covariant canonical operator formalism of a Weyl invariant (or equivalently, a locally scale invariant) gravity whose classical action consists of the well-known conformal gravity and Weyl invariant scalar-tensor gravity, on the basis of the Becchi-Rouet-Stora-Tyupin (BRST) formalism.

Beyond Silicon: Toward Sustainable, NIR‐II, and Conformable Organic Photodiodes

Advanced Energy Materials, EarlyView.
In this perspective, a strategic shift in organic photodetector (OPD) research is proposed: instead of the incremental advances in silicon's stronghold arena, the most impactful future for OPDs lies in addressing silicon's intrinsic limitations, i.e., detection in the longer wavelength range above silicon's coverage (>1100 nm, termed as near infrared ...

Insight‐Guided Optimization of the Individual Steps in Ambient Slot‐Die‐Coated Perovskite Solar Cells

Advanced Energy and Sustainability Research, EarlyView.
This graphical abstract presents an integrated workflow for optimizing perovskite thin film fabrication by tuning ink rheology, refining processing parameters, and controlling crystallization. Viscosity control and process optimization precisely regulate wet film thickness and drying time, while crystallization directed by solvent additives yields ...

Stereoisomerism‐controlled Packing in Ladder‐type Indacenodithieno[3,2‐b]thiophene Crystals

Aggregate, EarlyView.
Chirality dictates solid‐state behavior in ladder‐type indacenodithieno[3,2‐b]thiophene semiconductors. Enantiopure RR/SS‐ITMPEA forms more ordered packing and larger crystallites than racemic or achiral analogues, leading to nearly double photoconductivity as revealed by flash photolysis time‐resolved microwave conductivity.
