A First-Principles Study of Hydrostatic Pressure-Driven Semiconductor-to-Semimetal Transitions, Dynamic Stability, Thermodynamic and Optical Properties in phases (α and γ) of 2D SnTe Monolayer and Bilayer structure

This first-principles study reveals that hydrostatic pressure drives semiconductor-to-topological-nodal-line-semimetal transitions in $\alpha$ - and $\gamma$ -phase SnTe monolayers and bilayers, with bilayers exhibiting significantly lower critical pressures and enhanced dynamical stability due to interlayer coupling, thereby establishing these 2D structures as versatile platforms for tunable quantum and optoelectronic devices.

A Physicochemical Property-Based Predictive Model for Enhanced Oil Recovery Efficiency

This paper introduces a novel, physics-based predictive model for Enhanced Oil Recovery efficiency that utilizes exclusively measurable physicochemical properties and a chemical affinity term to achieve high accuracy (0.39% mean absolute error) across diverse flooding techniques without relying on arbitrary empirical factors.

Recovering the Standard Model Gauge Group from Loop Quantum Gravity: A Unified Relative-Entropy, Flux-Gauge Network, and Geometric-Engineering Construction

This paper presents a unified construction demonstrating how the Standard Model gauge group emerges from Loop Quantum Gravity by integrating a monotone relative-entropy renormalization group, a flux-gauge network model, and geometric engineering to derive the SU(5) breaking to SU(3)×SU(2)×U(1) via a vertex-Higgs mechanism, while rigorously proving key group-theoretic results and reporting numerical validations of the underlying coarse-graining dynamics.

Pervasive intervalley coherence in rhombohedral pentalayer graphene

Using scanning tunnelling microscopy, researchers demonstrate that intervalley coherence in rhombohedral pentalayer graphene is a pervasive, tunable instability that persists across a broad range of carrier densities and displacement fields, coexisting and competing with other correlated electronic states.

Topology-Guided Schur Recycling for Parametric Incompressible CFD of Separated Flows

This paper introduces CETER, a topology-guided Schur recycling framework that accelerates parametric incompressible CFD by algebraically reusing pressure-coupling mechanisms while employing persistent homology and residual checks to safely reject solver reuse when flow separation topology or algebraic consistency is compromised.

Geometry-Controlled Plasmonic Localization and Graphene-Assisted Thermal Redistribution in Hybrid Gold–Graphene Nanocylinder Arrays

This study demonstrates that integrating a graphene layer with gold nanocylinder arrays enables simultaneous optical enhancement through aspect-ratio-controlled plasmonic localization and thermal stabilization via graphene's superior lateral heat diffusion, effectively reducing temperature non-uniformity by over 92% while preserving strong plasmonic effects.

Temporal Slot Selection in an FRW Disformal Background under External Hubble-Constant Constraints

By applying external Hubble-constant constraints to a matched-complexity comparison of disformal FRW background models using Pantheon+, DESI, and cosmic-chronometer data, this study demonstrates that the temporal-only slot selection significantly outperforms the spatial-only branch by improving the data fit and maintaining better compatibility with external H0 calibration.
