This paper introduces a translation- and rotation-invariant Mesh Graph Neural Network (MGN) framework that successfully generalizes to predict von Mises stress fields in 2D structural components with arbitrary hole geometries and unseen load conditions, significantly outperforming conventional machine learning models in accuracy and adaptability for finite element analysis.
This paper presents an all-electron numerical atom-centered orbital implementation of the dynamical Bethe-Salpeter equation for extended systems, which incorporates dynamical screening effects and is validated through applications to molecular crystals like naphthalene.
This study employs atomistic simulations to reveal how size-dependent surface coordination and ligand passivation govern the electronic structure of stoichiometric HgTe quantum dots, demonstrating that neutral ligands effectively eliminate localized surface states and offer a chemical handle for engineering frontier states relevant to mid-infrared optoelectronics.
This paper numerically validates a nonlinear elasticity theory by demonstrating that shear banding in amorphous solids arises from a screened soft mode instability driven by topological screening and nonlinear coefficients, fundamentally distinguishing the phenomenon from fracture.
This study demonstrates that dimensional confinement in ultrathin diamane films, rather than intentional doping, can effectively stabilize the neutral charge state of group-IV vacancy color centers in diamond while preserving their favorable magneto-optical properties.
This study identifies monolayer VO with a buckled Lieb structure as a robust room-temperature 2D altermagnet that exhibits structural stability, auxetic behavior, a large momentum-dependent spin splitting of 1.2 eV, and significant intrinsic spin Hall conductivity.
This paper proposes an information-theoretic approach for predicting the phase stability of chemically disordered alloys by combining alchemical Monte Carlo sampling with a Graph Convolutional Neural Network model and an information entropy-based metric, demonstrating its effectiveness across binary to quinary systems where conventional methods face computational challenges.
This paper demonstrates that rolling a two-dimensional -wave altermagnet into a nanotube transforms its momentum-dependent spin splitting into a chiral-angle-controlled one-dimensional splitting following a dependence, thereby establishing dimensional projection as a general strategy for engineering spin-split quantum states in low-dimensional magnetic materials.
This study demonstrates that partial substitution of Gd³⁺ with smaller Er³⁺ ions in zircon-type Gd₁₋ₓErₓVO₄ systematically tunes lattice parameters and magnetic interactions, effectively optimizing the low-temperature magnetocaloric performance for cryogenic refrigeration, with the Gd₀.₉Er₀.₁VO₄ composition achieving a maximum magnetic entropy change of 45.1 J kg⁻¹ K⁻¹ under a 7 T field.
This paper demonstrates that bilayer WSe is the optimal channel for valley-engineered gate-all-around transistors because its near-thermal K- valley degeneracy at room temperature enables simultaneous enhancement of on-current and suppression of off-current via strain, while maintaining a subthreshold swing near the thermionic limit.
