High-entropy perovskites, architectured by s0/d0/d10 cations, as novel electrolytes for solid oxide fuel cells

This study demonstrates that high-entropy perovskite electrolytes engineered with mixed s⁰/d⁰/d¹⁰ cations, specifically (Ba₀.₅₀Sr₀.₅₀)(Ti₀.₃₃Zr₀.₃₃Sn₀.₃₃)O₃, serve as effective rare-earth-free materials for solid oxide fuel cells by achieving a maximum power density of 0.53 W·cm⁻² at 973 K through a tailored heterogeneous electronic structure and favorable oxygen vacancy formation.

Measuring momentum-resolved dissipation of phonon-polaritons in LiNbO $_3$ with terahertz driving

This paper introduces a THz pump-Raman probe technique to map the momentum-resolved dispersion and damping of phonon-polaritons in LiNbO $_3$ , revealing a nontrivial frequency dependence of the intrinsic damping rate through combined experimental and theoretical analysis.

Lattice initialisation and finite-size effects of non-equilibrium molecular dynamics simulations for heat transfer across graphene-copper interfaces

This study demonstrates that Kapitza resistance at graphene-copper interfaces in non-equilibrium molecular dynamics simulations is highly sensitive to lattice initialization and residual strain, which can cause a two-fold variation in thermal resistance through strain-dependent phonon spectral shifts and the formation of damping boundary layers, rather than being primarily determined by domain size or simple phonon spectral overlap.

Electrical Control of Altermagnetism in a Quasi-1D Magnet

This paper demonstrates that quasi-one-dimensional antiferromagnetic chains in the van der Waals magnet AgCrP $_2$ S $_6$ exhibit electrically controllable altermagnetism, where an external out-of-plane electric field induces a linear, sign-reversible nonrelativistic d-wave spin splitting driven by anisotropic interchain hoppings.

Operando observation of strain relaxation in fatigued pearlitic steel

Using operando Dark-Field X-ray Microscopy, this study reveals that while cementite lamellae in pearlitic railway steel suppress long-range dislocation motion and lattice rotation, they still allow for significant elastic strain relaxation via short-range dislocation annihilation at temperatures as low as 250°C, explaining the material's macroscopic softening under service conditions.

Point Group Equivariant Graph Neural Networks for Materials

This paper introduces Point-Group Equivariant Graph Neural Networks (PGEqNN), an architecture that leverages specific point-group symmetries and restricts filter functions to trivial subspaces to achieve the same or better predictive accuracy for material properties as full $O(3)$ -equivariant models while using significantly fewer parameters.

The crystallographic quaternions and their product law

This paper introduces crystallographic quaternions by generalizing the quaternion product law to work directly within crystal bases using a "cross tensor" derived from the metric tensor, thereby eliminating the need for coordinate transformations when calculating rotation compositions in crystallography.

Baldereschi mean value points for three-dimensional Bravais lattices

This paper evaluates and tabulates the Baldereschi mean-value points for all fourteen three-dimensional Bravais lattices, providing essential wavevectors that approximate the Brillouin zone average for both one-electron methods and explicitly correlated many-electron simulations like quantum Monte Carlo.

First-principles electron-phonon scattering in real-time TDDFT

This paper presents a first-principles dissipative real-time TDDFT framework that incorporates electron-phonon scattering via self-energy-derived collision integrals, enabling the simulation of irreversible relaxation, decoherence, and time-resolved spectroscopic signatures in laser-driven crystalline materials.
