Electrostatic gating directly manipulates the electronic flat bands and van Hove singularities in single-layer molecular kagome lattices, enabling unprecedented control over quantum phenomena in 2D materials.

Future collider design can now leverage a GPU-accelerated, open-source particle-in-cell code that matches established simulation accuracy for complex beam-beam interactions.

The canonical $2 \times 2$ triple-$q$ charge-density wave in 1T-TiSe$_2$ is not simultaneous but a sequential emergence of inequivalent subcomponents, overturning a 50-year paradigm.

Breaking inversion symmetry is normally assumed to unleash even-order optical responses, but hidden bipartite particle-hole symmetry can suppress them entirely—unlocking photo-induced, pure spin currents with virtually no parasitic charge flow.

Optical spectral peaks are not proof of exciton localization—nanoscale imaging reveals that atomic-scale structural reconstruction and strain are the true drivers of exciton confinement in moiré superlattices.

Foundation interatomic potentials often suffer from inconsistent benchmarks due to infrastructure fragmentation, but QuAcc eliminates this methodological drift by decoupling pure quantum chemistry workflows from the underlying orchestration engines.

Dopant site assignments in atom probe tomography can be fundamentally distorted by preferential field evaporation, proving that direct spatial reconstructions risk misidentifying atomic-scale defects without evaporation-field corrections.

Rapid, zero-setup segmentation of X-ray tomography data can transform how researchers interpret complex material microstructures in real-time.

Achieving competitive computational efficiency in Hartree-Fock theory while allowing for flexible orbital locality could revolutionize molecular simulations.

Widely used approximations for modeling hot-exciton relaxation in semiconductor nanocrystals can fail, but mapping surface hopping (MASH) offers a more reliable alternative.

Entangled photons let you selectively excite specific biexciton states in quantum dots, opening new doors for quantum control.

Turns out language models don't need the whole knowledge graph to generate scientific hypotheses—a compact subgraph often works just as well.

VLMs struggle to interpret quantum computing calibration plots, with many open-weight models *worsening* in performance when given multiple example plots in context.

Injecting local topological structure into neural networks via persistence-based data augmentation unlocks improved performance and interpretability in histopathology image classification and 3D material regression.

Core excitons in NaF decohere in under 8fs, and polarization-controlled attosecond spectroscopy reveals that bright excitons have s-like symmetry while dark excitons have p-like symmetry.

Helium rain in gas giants may be less frequent than we thought, thanks to new simulations that significantly lower the estimated hydrogen-helium demixing temperatures.
