First-principles-based Prediction of Phase Fields: Part I. Binary and Ternary Refractory Alloys

This paper presents a computationally efficient, first-principles-based framework that combines DFT-calculated binary mixing enthalpies with sub-regular solution models to accurately predict phase fields and solvus boundaries in complex refractory multiple principal element alloys without requiring higher-order interaction fitting, thereby enabling scalable high-throughput design and interactive exploration of their phase diagrams.

Electronic correlations and fluctuating lattice distortions in vanadium dioxide

This paper introduces a stochastic semiclassical extension of dynamical mean-field theory that self-consistently couples correlated electrons with fluctuating lattice distortions to reveal that the metal-insulator transition in vanadium dioxide involves two distinct melting events: a dimerization driven by electron coupling and a structural restoration driven by lattice entropy.

Revealing the origin of ionic conduction in silver-iodide-doped silver phosphate glass

By employing time-domain terahertz spectroscopy on silver-iodide-doped silver phosphate glasses, this study reveals that ionic conduction emerges from a crossover to short-range dispersive transport only when high carrier density and bond-bending polarization are embedded within a sufficiently soft glassy matrix, rather than from bound polarization alone.

Collective Excitonic Structure Governs Anomalously Weak Thermal Optical Dephasing in Conjugated Polymers

Using two-dimensional electronic spectroscopy, this study reveals that a diverse series of conjugated polymers exhibits anomalously weak thermal optical dephasing governed by collective excitonic structure, while demonstrating that the absolute homogeneous linewidth varies depending on whether coherence- or population-detected measurements are employed.

Spin--orbit-enhanced correlation sensitivity and anomalous magnetic response in non-dimerized 4d44d^4 ilmenite CdRuO3_3

This study reports the synthesis and characterization of non-dimerized CdRuO3_3, demonstrating that spin-orbit coupling significantly enhances electron correlation sensitivity to open a small insulating gap and produce an anomalous magnetic response inconsistent with simple metallic or spin-only models.

Scalable machine learning framework for multiphase identification from powder X-ray diffraction

The paper introduces GALAXI, a scalable machine learning framework that decouples multiphase X-ray diffraction identification into independent binary classifiers and Rietveld refinement, achieving high accuracy and robustness against experimental artifacts while enabling the use of massive crystallographic databases without retraining.

Self-Trapping Enabled Highly Bright Momentum-Indirect Interlayer Excitons

This paper demonstrates that coupling 2D perovskites with monolayer transition metal dichalcogenides enables highly bright momentum-indirect interlayer exciton emission with quantum yields exceeding 60%, a phenomenon driven by self-trapping induced by strong exciton-phonon coupling in the soft perovskite lattice.

Formation of grain boundaries in ductile single crystals under plane-strain simple shear: a block-coordinate finite element method

This paper investigates the spontaneous formation of lamellar grain boundaries in ductile single crystals under plane-strain simple shear by employing a polyconvex continuum dislocation theory and a specialized block-coordinate finite element method to numerically resolve the microstructure arising from energy non-quasiconvexity and gradient regularization.

Excitons probe intrinsic flat band Mottness in a van der Waals heterostructure

By combining gate-tunable optical spectroscopy with first-principles calculations, this study demonstrates that excitons in monolayer WSe2_2 serve as a sensitive probe for intrinsic flat-band Mott physics in adjacent Nb3_3Cl8_8, revealing correlation-reconstructed gaps, the formation of polaronic quasiparticles, and valley-selective coupling driven by spin-polarized states.
