Electronic correlations and spin-charge-density stripes in double-layer La3_3Ni2_2O7_7

Using \emph{ab initio} and DFT+DMFT methods, this study reveals that electronic correlations in pressurized La3_3Ni2_2O7_7 drive a transition to a narrow-gap insulating state characterized by double spin-charge-density stripes and cooperative lattice distortions, suggesting that fluctuations in these stripe patterns are crucial for tuning the material's superconductivity.

Defects and Impurity Properties of VN precipitates in ARAFM Steels: Modelling using a Universal Machine Learning Potential and Experimental Validation

This study combines machine learning potentials, density functional theory, and experimental validation to reveal that while ordered nitrogen vacancies in VN precipitates mitigate irradiation damage in ARAFM steels, solute additions like chromium disrupt this ordering and accelerate precipitate dissolution under fusion-relevant conditions.

The viscoelastic rheology of transient diffusion creep

This paper presents a simple finite element model of transient diffusion creep in polycrystalline materials, demonstrating that its linear viscoelastic behavior can be effectively described by an extended Burgers model where the high-frequency Andrade exponent is determined by grain junction geometry, though the model provides only a lower bound for attenuation observed in laboratory experiments due to unaccounted dissipative processes.

Uncovering surface states of the Dirac semimetal BaMg2Bi2

By combining high-resolution angle-resolved photoemission spectroscopy with density functional theory calculations, this study reveals previously unobserved topologically trivial surface states in the Dirac semimetal BaMg2Bi2, thereby reconciling discrepancies between prior experimental and theoretical results and providing a comprehensive understanding of its low-energy electronic structure.

Emergence of Kondo-assisted Néel order in a Kondo necklace model

This paper demonstrates that in a spin-only Kondo necklace model realized in a Ni-based complex, Kondo coupling to spin-1 moments mediates effective antiferromagnetic interactions that stabilize Néel order, establishing a universal boundary where Kondo interactions suppress magnetism for spin-1/2 but enhance it for spin-1 and higher.
