Origins of Universal Machine Learning Force-Field Errors in Multicomponent Materials

This study benchmarks eleven universal machine learning force fields against density functional theory across 7,599 multicomponent configurations to identify that generalization errors are primarily driven by training-reference coverage gaps, local geometric heterogeneity, and a distinct asymmetry where compression-induced force errors significantly exceed those from extension.

Optimization-Based Thickness Estimation and Depth-Resolved FIB-Induced Damage Characterization via Multislice Electron Ptychography

This paper demonstrates that joint Bayesian optimization of specimen thickness and other parameters within multislice electron ptychography enables accurate, self-consistent estimation of local lamella thickness and depth-resolved characterization of FIB-induced amorphous damage from a single 4D-STEM dataset.

Quasicrystalline oxide interfaces by twisting SrTiO3 membranes

This paper demonstrates that twisting epitaxial SrTiO3 membranes by specific angles (45° for bilayers and successive 30° for trilayers) creates strongly bonded, long-range ordered octagonal and dodecagonal quasicrystalline interfaces with unique electronic reconstructions and nonlinear optical responses, establishing a deterministic route for engineering quasiperiodic order in complex oxides.

The Role of THz Phonons in the Ionic Conduction Mechanism of Li7La3Zr2O12Li_7La_3Zr_2O_{12} Polymorphs

Using laser-driven ultrafast impedance spectroscopy, this study demonstrates that resonantly exciting low-energy THz phonons enhances ionic conductivity in both cubic and tetragonal phases of Li7La3Zr2O12Li_7La_3Zr_2O_{12} by dynamically modulating ion hopping pathways and increasing migration entropy, independent of the material's static structural properties.

Integrated on-chip quantum light sources on a van der Waals platform

This paper presents a scalable, integrated van der Waals photonic platform that combines strain-engineered bilayer WSe2_2 quantum emitters with WS2_2 waveguides and grating couplers to achieve efficient, high-purity on-chip single-photon emission with a measured g(2)(0)g^{(2)}(0) as low as 0.003.
