This paper introduces two efficient computational routes to calculate the thermodynamic factor for non-dilute diffusion in multicomponent alloys by accounting for vacancy-mediated free energy curvature, thereby enabling accurate and resource-efficient predictions of diffusion matrices for use in mesoscale mass transport simulations.
Using density functional theory, this study demonstrates that charge disproportionation in SmNiO serves as a novel mechanism to screen polar discontinuities at interfaces with ferroelectric BaTiO by redistributing electrons and altering the nickel oxidation states to compensate for interface charges.
This paper analytically investigates the linear dielectric response of antiferromagnetic multiferroics with cycloidal equilibrium and weak ferromagnetism, deriving the dynamical electric susceptibility tensor to demonstrate how noncollinear spin-induced polarization, low-frequency gapless spin waves, and the spiral structure influence the system's reaction to alternating electric fields.
This study utilizes ReaxFF molecular dynamics and experimental validation to demonstrate that layer topology and interfacial mechanical confinement are critical design variables for optimizing ferroelectric switching in ZnO/Zn1-xMgxO heterostructures, revealing that specific architectural arrangements can significantly reduce the required switching field through stress-assisted cooperative pathways.
This paper introduces Gaussian Splatting for Density Functional Theory (GS-DFT), a novel method that represents molecular orbitals as an optimized cloud of Gaussians to achieve high accuracy with significantly fewer parameters and quadratic memory scaling, enabling the simulation of large systems up to 2,742 atoms on a single four-GPU node.
This XPS study reveals that the early-stage oxidation of pure Zr single crystals is crystallography-dependent, with near-prismatic orientations oxidizing faster and forming thicker oxide films containing a homogeneous distribution of sub-oxides compared to basal orientations, while both follow a three-stage logarithmic kinetics.
The paper introduces Sinter-PiNDiff, a retrainable physics-integrated neural differentiable framework that accurately predicts sintering density and grain-size evolution across diverse material systems with sparse data, outperforming standard neural network baselines while highlighting the critical role of density-dependent kinetic feedback.
This paper establishes a unified microscopic framework explaining the diverse magnetic behaviors in isoelectronic chromium monopnictides (CrSb, CrAs, CrP) by demonstrating how chemical pressure drives structural distortions and itinerancy changes that reconstruct competing exchange interactions, thereby transforming a common high-spin spin-fermion electronic structure into distinct magnetic phases ranging from altermagnetism to frustrated disorder.
Using time-resolved multi-terahertz spectroscopy, researchers observed an ultrafast, non-thermal electronic phase change in SnSe driven by 1.55 eV photoexcitation, characterized by bimodal conductivity dynamics and a macroscopic band gap collapse occurring above a critical fluence of approximately 6 mJ/cm².
This study utilizes numerical and analytical modeling to demonstrate that cohesion significantly influences low-speed oblique impacts on granular media under low gravity, revealing that current scaling laws are insufficient and highlighting the need for new dimensionless parameters to accurately capture the complex interplay between cohesion, friction, and gravitational conditions.
