Disentangling the Discrepancy Between Theoretical and Experimental Curie Temperatures in Ferroelectric PbTiO $_3$

This study identifies that the underestimation of the Curie temperature in ferroelectric PbTiO $_3$ primarily arises from limitations in exchange-correlation functionals rather than machine learning force field inaccuracies, revealing that apparent improvements from short-range models are fortuitous error cancellations while accurate predictions require explicit long-range interactions and improved functionals.

Open Materials Generation with Inference-Time Reinforcement Learning

This paper introduces OMatG-IRL, a novel policy-gradient reinforcement learning framework that operates directly on velocity fields of continuous-time generative models to enable efficient, target-property-aligned crystal structure prediction without requiring explicit score computation.

Strain-Driven Altermagnetic Spin Splitting Effect in RuO $_2$

This study resolves inconsistencies in experimental reports on RuO $_2$ by demonstrating that while bulk and certain thin-film orientations are nonmagnetic, strain-induced altermagnetic spin splitting in specific (100) and (110) orientations generates a strong spin Hall effect without requiring Hubbard $U$ corrections.

Screening of the Coulomb interaction in Carbon Nanotubes: A First-Principles cRPA study

This first-principles cRPA study reveals that the electronic screening and effective Coulomb interactions in carbon nanotubes are governed not only by metallicity but also sensitively by chirality and band topology, resulting in interaction strengths 2–3 eV lower than in nanoribbons and explaining the reduced exciton binding energies observed experimentally.

Range-Aware Bayesian Optimization for Discovering Diverse Designs within Target Property Windows

This paper introduces a range-aware Bayesian optimization framework that efficiently discovers diverse designs satisfying target property ranges by directly scoring the posterior probability of range compliance, demonstrating superior performance over standard methods in both benchmarks and practical materials design case studies.

Chiral Magnons and Cycloidal Phonons in Altermagnetic CuF $_{2}$ Monolayer

This study demonstrates that monolayer CuF $_2$ serves as a unique altermagnetic platform where $P2_1/c$ symmetry simultaneously governs chirality-split magnons with quantized Chern numbers and cycloidal phonons, revealing a directional complementarity between spin and lattice chiral responses.

Unveiling Orbital-mediated Ultrafast Demagnetization in Rare Earth-Transition-Metal Ferrimagnets

This study establishes that the speed of ultrafast demagnetization in Rare Earth-Transition-Metal ferrimagnets is governed by a universal orbital-mediated mechanism where the competition between 3d and 4f spin-orbit coupling channels determines whether angular momentum dissipates via rapid direct orbital-to-lattice transfer or slower multi-step pathways.

Ambient and Pressure Dependent Superconductivity with Hydrogen Storage Potential in Quaternary Hydride LiMgZr2H12: A Comprehensive First-principles Insights

This first-principles study predicts that the quaternary hydride LiMgZr2H12 is a mechanically and dynamically stable superconductor with a critical temperature of 72.76 K at ambient pressure (enhanced to 77.3 K at 10 GPa) and a high gravimetric hydrogen storage capacity of 5.36 wt%, making it a promising candidate for both ambient-condition superconductivity and hybrid hydrogen storage applications.
