Observation of ν = 5/2 Fractional Quantum Hall Effect in Trilayer Graphene Proximitized by V‐Doped WSe2

Advanced Materials, EarlyView.
Even‐denominator 5/2 fractional state in trilayer graphene/V‐doped WSe2 heterostructure, mediated by proximitized magnetism, is demonstrated. An exceptionally high energy gap ∆5/2 (48 K) for the 5/2 state, significantly surpassing previous values in semiconductors and bilayer graphene (∆5/2 < 1 K) is reported.

Inverse Spillover and Dimensionality Effects on Interstitial Hydrogen

Advanced Materials Interfaces, EarlyView.
Interstitial hydrogen behaves distinctly at interfaces compared to the bulk. Vanadium films show proximity‐dependent hydrogen depletion near interfaces–an inverse of hydrogen spillover. Ion beam and resistivity measurements reveal Fe/V‐superlattices have lower hydrogen solubility and higher critical temperature than Cr/V due to proximity‐induced finite

Scalable Programming of LaAlO3/SrTiO3 Interfaces via Ultra‐Low‐Voltage Electron‐Beam Lithography

Advanced Materials Interfaces, EarlyView.
Ultra‐low‐voltage electron beam lithography (ULV‐EBL) enables rapid and scalable patterning of LaAlO3/SrTiO3 interfaces into nanowires, barriers, and waveguides that reveal 1D superconductivity, nonlinear current‐voltage response, and ballistic transport.

Measurement of the azimuthal angle dependence of inclusive jet yields in Pb+Pb collisions at √sNN=2.76  TeV with the ATLAS detector [PDF]

, 2013
Measurements of the variation of inclusive jet suppression as a function of relative azimuthal angle, Δϕ, with respect to the elliptic event plane provide insight into the path-length dependence of jet quenching.

Airbrushing: A Novel Method for Preparation of High‐Emissivity Black Coating for Infrared Measurements

Advanced Materials Interfaces, EarlyView.
This study showcases the airbrush method, a novel coating technique for the preparation of thin black paint coatings for infrared camera measurements. Using the method, coatings with an emissivity of 0.95, and as thin as 3 µm can be prepared. The method is affordable, non‐destructive, and can be prepared onto a wide range of substrates while ...

The Exoplanet Edge: Planets Do Not Induce Observable Transit Timing Variations with a Dominant Transit Timing Variation Period Faster than Half Their Orbital Period

The Astrophysical Journal Letters
Transit timing variations (TTVs) are observed for exoplanets at a range of amplitudes and periods, yielding an ostensibly degenerate forest of possible explanations.

Impact of Grain Size on Low‐Temperature Carrier Phase Coherence Length in Polycrystalline Halide Perovskite Films

Advanced Materials Interfaces, EarlyView.
Magnetoresistance measurements on a series of polycrystalline cesium tin iodide (CsSnI3) thin film devices having varying grain sizes reveal no power law dependence with clear signatures of weak anti‐localization (spin‐orbit coupling). Surprisingly, the extracted phase coherence lengths are found to be independent of grain sizes.

Multilingual performance of a multimodal artificial intelligence system on multisubject physics concept inventories

Physical Review Physics Education Research
We investigate the multilingual and multimodal performance of a large language model-based artificial intelligence (AI) system, GPT-4o, using a diverse set of physics concept inventories spanning multiple languages and subject categories. The inventories,

Shaping Microbial Motion with Light: A Contactless Approach Using Diffusioosmotic Flow

Advanced Materials Interfaces, EarlyView.
Light‐controlled, contactless manipulation of cyanobacteria using photoresponsive azobenzene surfactants. Reversible photo‐isomerization generates surface flow, enabling precise trapping, relocation, and directional control of single cells or ensembles with adjustable light intensity and wavelength for noninvasive, spatiotemporally resolved microbial ...
