Correlated Metal LaNiO3 as a p‐Type Transparent Conductor

Advanced Functional Materials, EarlyView.
p‐type transparent conducting oxides are needed to enable superstrate solar cell geometries with n‐type absorbers. The p‐type correlated metal LaNiO3 combines high optical transmission with low electrical resistivity and is compatible with a range of scalable deposition processes.

Multizone Modeling of Black Hole Accretion and Feedback in 3D GRMHD: Bridging Vast Spatial and Temporal Scales

The Astrophysical Journal
Simulating accretion and feedback from the horizon scale of supermassive black holes (SMBHs) out to galactic scales is challenging because of the vast range of scales involved. Elaborating on H.

Synergistic Solar Interfacial Evaporation and Photocatalysis Enabled by a Hierarchical Porous Hydrogel Reactor

Advanced Functional Materials, EarlyView.
A tree‐inspired hydrogel interfacial reactor couples solar evaporation with photocatalysis for simultaneous desalination and waste water treatment. The bilayer design achieves 2.14 kg·m−2·h−1 evaporation rate with 79% dye degradation under one sun, demonstrating that photothermal heating and evaporation induced pollutant enrichment create a self ...

Giant Electrostriction in Halide Perovskites Revisited With Double‐Modulation Interferometry

Advanced Functional Materials, EarlyView.
A giant electrostrictive effect in lead halide perovskites had been reported previously. This work uses sensitive interferometry to measure the electromechanical response of various halide perovskite samples. The results reveal no intrinsic electrostrictive compression. Instead, the materials expand primarily under an applied electric field as a result

Can black holes preserve 𝒩 > 4 supersymmetry?

Journal of High Energy Physics
The dynamics of near-BPS black holes are governed by the breaking of the conformal symmetry that emerges near their horizons. Using the classification of superconformal symmetries, we systematically classify and quantize all effective theories that can ...

Multimode Oxide‐Based Optoelectronic Memtransistor for In‐Sensor Vision Processing

Advanced Functional Materials, EarlyView.
A multimode optoelectronic memtransistor (OEMT) is demonstrated for vision explainable artificial intelligence (VXAI) hardware. By integrating optical sensing, electrical masking, and non‐volatile memory, the device enables key operations required for generating saliency information.

Supersymmetry breaking in SYK and the black hole spectrum

Journal of High Energy Physics
The spectrum and dynamics of near-extremal black holes is strongly modified by quantum effects at low temperatures. When the extremal limit does not preserve any supersymmetry, the density of states goes to zero at extremality and no extremal black holes

Mechanistic Control of C─H Bond Activation and C─C Coupling in Light‐Driven Methane Conversion to C2+ Products over Multifunctional Photocatalysts

Advanced Functional Materials, EarlyView.
Methane photocatalytic activation under mild conditions remains a formidable challenge in the synthesis of solar fuels. In this review, we emphasize the growing importance of multifunctional materials and hybrid systems within a unified mechanistic framework that integrates selective C─H bond activation, formation and control of intermediates, C─C ...

Spectrum of BPS black holes in AdS3 × S 3 × S 3 × S 1

Journal of High Energy Physics
We uncover novel features in the spectrum of BPS and near-BPS states in asymptotically AdS3 × S 3 × S 3 × S 1 spacetimes. This follows from a careful analysis of semiclassical and quantum black holes in this theory, which have peculiarities due to the ...
