A Parameter-Free Reference Hamiltonian for Tight-Binding Vanadium Oxides

This paper introduces a parameter-free tight-binding reference Hamiltonian for vanadium oxides that overcomes the large, offsetting errors of standard second-order methods by deriving from superposed neutral atoms and full PBE potentials, thereby achieving high accuracy in energy differences and charge responses while clarifying that symmetry breaking in Magnéli phases requires explicit electron-lattice or spin-correlation terms.

Collision Cascade Morphology and Defect Nucleation in Pure Tungsten and an Equimolar Refractory W-Ta-Cr-V Alloy

Molecular dynamics simulations using machine-learning potentials reveal that the equimolar W-Ta-Cr-V refractory high-entropy alloy exhibits superior resistance to primary irradiation damage compared to pure tungsten, as its light elements promote cascade splitting into subcascades and accommodate defects as point defects rather than forming dislocation loops or voids.

Bulk superconductivity in quintuple-layer square-planar nickelate La6Ni5O12

This paper reports the discovery of bulk superconductivity at ambient pressure in the quintuple-layer square-planar nickelate La6Ni5O12, synthesized via topotactic reduction, which exhibits an onset transition temperature of approximately 18 K and a superconducting volume fraction of ~25%, thereby establishing a crucial platform for investigating the mechanism of high-temperature superconductivity in nickelates.

Room-Temperature Metallic 2D Ferromagnetism Stabilized by Quantum Metric

This paper proposes that the uniform room-temperature metallic ferromagnetism observed in the layered electride YCl is stabilized by a prominent quantum metric near topological band crossings, which redirects the system's instability from density-wave states to ferromagnetic order and predicts a Curie temperature well above room temperature.

High-Harmonic Generation Probes Quantum Nuclear Fluctuations in Liquid Water

This study demonstrates that high-harmonic generation spectroscopy, when combined with path-integral molecular dynamics, can detect and characterize nuclear quantum fluctuations in liquid water by revealing how quantum nuclear delocalization suppresses harmonic yields and induces interference minima through hydrogen-bond-induced valence-band broadening.

Emergent medium-range order in amorphous silicon

Through large-scale machine-learning simulations, this study reveals that medium-range order in amorphous silicon arises from a crossover between local bonding constraints and emergent cubic/octahedral symmetries at larger distances, unifying the first sharp diffraction peak, topological ring correlations, and orientational order into a single structural framework driven by the interplay of local bonding and efficient packing.

Seismology of Glasses

This paper proposes a unified theory modeling glass relaxation as a combination of local rearrangements and their long-ranged viscoelastic "seismic" disturbances, successfully explaining the transition from compressed to stretched exponential relaxation observed in dynamical structure factors.

Evidence for hidden order and its potential correlation with electron-hole asymmetry in iridate superlattices

This study reports the discovery of a hidden order in hole-doped iridate superlattices that emerges above the Néel temperature and explains the observed electron-hole asymmetry in the coupling between insulating and antiferromagnetic states, distinguishing it from structural origins.

Signatures of symmetry-stabilized Dirac fermions in correlated oxide CaNbO3 thin films

This study demonstrates that oxygen octahedral rotations in epitaxial CaNbO3 thin films serve as a symmetry-control parameter to stabilize topological Dirac fermions, evidenced by high-mobility metallic transport, Shubnikov-de Haas oscillations, and strain-driven band structure evolution from nodal-line to Dirac-electron features.
