A Hybrid GNN-FEM Framework for Phase-Field Fracture Simulation. Physics-Preserving Hybridization for Generalizable Surrogate Modeling

This paper proposes a hybrid GNN-FEM framework that integrates a graph neural network surrogate for phase-field updates within a conventional finite element staggered scheme, enabling efficient, accurate, and generalizable simulations of history-dependent fracture evolution across diverse geometries and conditions while preserving physical consistency.

Moreau-Yosida-based Kohn-Sham Inversion for Periodic Systems

This paper establishes a theoretical and numerical framework for density-potential inversion in periodic systems using Moreau-Yosida-regularized density-functional theory, leveraging lower semicontinuity of the kinetic-energy functional and proximal mappings to recover exchange-correlation potentials for Kohn-Sham and Gross-Pitaevskii equations.

Charge-state control of carbon-related optical absorption in AlN

By combining photo-induced electron paramagnetic resonance, optical absorption spectroscopy, and hybrid functional calculations, this study identifies the neutral charge state of substitutional carbon on the nitrogen site (CN_N) as the microscopic origin of the widely observed sub-bandgap optical absorption in AlN between 2 eV and 4 eV.

Enhanced electronic correlations and altermagnetic ground state of two-dimensional CsCr3Sb5 monolayers

This study employs first-principles calculations to demonstrate that two-dimensional CsCr3Sb5 and Cr3Sb5 monolayers exhibit enhanced electronic correlations and an altermagnetic ground state, characterized by the simultaneous proximity of flat bands and van Hove singularities to the Fermi level, which can be further tuned via tensile strain.

Thickness-Dependent Interlayer Coupling and Semiconductor-to-Semimetal Crossover in Arsenene Multilayers

By combining diffusion quantum Monte Carlo and density functional theory, this study reveals that interlayer coupling in arsenene multilayers is thickness-dependent rather than solely registry-determined, leading to a structural evolution from A1_{1}A1_{1} to bulk-like A1_{1}B−1_{-1} stacking and a concurrent semiconductor-to-semimetal crossover driven by enhanced interlayer As pz_{z} hybridization.

Interplay of Altermagnetism and Coupled Quasi-Altermagnetic states in Sliding Two-dimensional Square Lattice

This paper proposes a new classification of altermagnetic states in two-dimensional square lattices, identifying a distinct "coupled quasi-altermagnetic" phase where interlayer sliding controls reversible non-relativistic spin splitting, and demonstrates this mechanism using Mn2WS4 and its Janus derivative Mn2WS2Se2.

Terahertz frequency upconversion by coherently driving charge dynamics in the InSb/CdTe heterostructure

This paper demonstrates efficient in-plane magnetic field-induced second-harmonic generation and significant third-harmonic generation in an InSb/CdTe heterostructure, attributing these effects to orbital-Zeeman corrections and Drude-like charge dynamics to establish a general route for terahertz frequency upconversion in high-mobility materials.

Hartree-Fock Limit for Energies in Solids

This study presents a refined linearized augmented plane wave (LAPW) method that consistently constructs radial basis functions and core orbitals with the Hartree-Fock Hamiltonian to achieve micro-Hartree precision in total energies, thereby providing rigorous all-electron benchmarks for semiconductors and insulators while validating the practical accuracy of standard semi-local approaches for relative energies.

On representation of macroscopic crack in periodic fine-scale discrete mechanical models

This study evaluates novel boundary conditions for representing macroscopic cracks in periodic discrete models of concrete, finding that while Tessellation boundary conditions consistently produce well-defined localization bands, Percolation-path-aligned conditions suffer from spurious multi-band formation and displacement-jump augmented circular models sometimes fail to improve upon standard periodic results.
