This study utilizes first-principles calculations to demonstrate that the elastic moduli of the Ti2AlC MAX phase undergo significant thermal-induced softening, with bulk and shear moduli reductions of 15–29% and 13–31% respectively, under high-pressure (10–30 GPa) and high-temperature (300–1200 K) conditions.
This paper presents experimental and theoretical evidence for the formation of three-atom-thick gold structures in break-junction systems and introduces a robust method for calibrating atomic-scale distances and assessing electrode sharpness using these structures as a benchmark.
This study identifies Ba4YbReWO12 as a Jeff = 1/2 frustrated triangular lattice antiferromagnet that exhibits a dynamic, disordered ground state with short-range spin correlations down to 43 mK, lacking any signatures of long-range magnetic ordering or spin freezing.
In this reply to a comment regarding the crystal structure of Ba2MnTeO6, the authors acknowledge the ongoing debate between trigonal and cubic space groups but assert that their primary findings on the material's magnetic properties and spin dynamics remain robust and independent of the specific structural assignment, while calling for further high-resolution studies to definitively resolve the structural intricacies.
Through a combination of thermodynamic, spectroscopic, and scattering techniques, this study establishes MgCrGaO4 as a rare three-dimensional classical spin liquid characterized by the absence of magnetic order down to 57 mK, the emergence of antiferromagnetic short-range correlations, and gapless algebraic excitations.
This paper resolves the Blanc-Cances instability of the Wang-Teter nonlocal kinetic energy density functional in isolated systems by introducing a density-functional-dependent kernel, thereby achieving an order-of-magnitude accuracy improvement for single atoms while maintaining superior performance in bulk metals.
The paper introduces the AiiDAlab Quantum ESPRESSO app, a web-based platform that democratizes access to complex density functional theory calculations by integrating user-friendly graphical interfaces, automated workflows, and interactive visualization tools to overcome traditional barriers in software installation, setup, and analysis.
Using high-resolution momentum-resolved electron energy-loss spectroscopy combined with machine learning-enhanced molecular dynamics, this study demonstrates that chiral polar vortex lattices in PbTiO imprint their unique topological symmetry onto the material's vibrational spectrum, creating distinctive asymmetrical phonon shifts and revealing how topological defects restore trivial vibrational modes.
This paper introduces a unified many-body perturbation theory based on a Keldysh-Lindblad formalism that treats dissipation, correlations, and external driving on equal footing, enabling the systematic extension of established numerical methods like the Kadanoff-Baym equations to simulate driven, dissipative quantum materials with enhanced quasiparticle lifetimes.
This study combines density functional theory and bond-order potential simulations to reveal that hydrogen and copper vacancies cosegregate at copper grain boundaries, forming stable complexes that significantly lower hydrogen diffusion barriers and facilitate rapid accumulation, thereby elucidating the atomistic mechanism of hydrogen embrittlement.
