Advanced Functional Materials, EarlyView.Combinatorial vapor deposition enables independent tuning of Cs/Pb and Br/Cl in wide‐bandgap perovskites. Automated multimodal mapping of 500+ compositions reveals a high‐energy optical transition that correlates with enhanced photoluminescence, defining a practical Cs/Pb window.

Local discrete symmetries from superstring derived models [PDF]
, 1996 Discrete and global symmetries play an essential role in many extensions of the Standard Model, for example, to preserve the proton lifetime, to prevent flavor changing neutral currents, etc.

Memristive‐Gated RC‐Delay Synaptic Transistors for Time‐Encoded Analog in‐Memory Computing
Advanced Functional Materials, EarlyView.A Memristive‐Gated Transistor for Time‐Encoded Analog In‐Memory Computing — By exploiting the RC delay of a self‐rectifying interface‐type memristor, nonlinear I–V distortion is structurally bypassed, enabling 3‐bit nonvolatile memory, spike‐timing‐based analog encoding, and hardware‐calibrated reservoir‐computing validation within a unified device ...

Flavor symmetries from modular subgroups in magnetized compactifications
Journal of High Energy PhysicsWe study the flavor structures of zero-modes, which are originated from the modular symmetry on T 1 2 × T 2 2 $$ {T}_1^2\times {T}_2^2 $$ and its orbifold with magnetic fluxes. We introduce the constraint on the moduli parameters by τ 2 = Nτ 1, where τ i

2D Co‐Assembly of Solid Acids Enables Stable Superprotonic Conduction Above 260°C
Advanced Functional Materials, EarlyView.A two‐dimensional co‐assembly strategy integrates antimony phosphate and phosphotungstic acid nanosheets into free‐standing inorganic lamellar membranes with confined acid–acid interfaces. The resulting interfacial hydrogen‐bond network enables anhydrous proton conductivity exceeding 0.1 S cm−1 at 260°C and supports stable high‐temperature fuel‐cell ...

Relativistic Planck-scale polymer
Physics Letters B, 2017 Polymer quantum mechanics has been studied as a simplified picture that reflects some of the key properties of Loop Quantum Gravity; however, while the fate of relativistic symmetries in Loop Quantum Gravity is still not established, it is usually ...

Bone‐Inspired Recyclable Composites for Damage‐Tolerant Circular Materials
Advanced Functional Materials, EarlyView.Bone‐inspired architected composites are developed by combining osteon‐like reinforcements with a recyclable Elium thermoplastic matrix. The hierarchical architecture redirects cracks and promotes energy dissipation, while enabling recovery of intact, aligned, load‐bearing reinforcement units that retain their original stiffness, revealing a route ...

Advanced Functional Materials, EarlyView.HfxZr1−xO2${\rm Hf}_x{\rm Zr}_{1-x}{\rm O}_2$ offers CMOS‐compatible nanoscale ferroelectricity yet suffers from a high Ec${\rm E}_c$ demanding large operating voltages. A unified phase‐field framework spanning AFE/FE/DE phases shows how FE grains soften neighboring AFE grains over λ$\lambda$ ≈$\approx$ 22–37 nm.

Higher structure of non-invertible symmetries from Lagrangian descriptions
Journal of High Energy PhysicsThe symmetry structure of a quantum field theory is determined not only by the topological defects that implement the symmetry and their fusion rules, but also by the topological networks they can form, which is referred to as the higher structure of the
