Below are the latest papers in condensed matter and materials science, organized by their most recent publication dates.
Using machine-learning interatomic potentials, this study reveals that grain-boundary segregation of group-VI elements (Cr, Mo, W) and Zr in high-entropy transition metal carbides induces interfacial premelting at temperatures significantly lower than the bulk melting point, with Cr-rich boundaries exhibiting the earliest and most extensive disordering.
This study reveals that dislocation absorption at grain boundaries can drive a conservative, diffusionless climb of disconnections through localized grain boundary phase transformations, offering a mechanism distinct from conventional vacancy-mediated processes.
This paper establishes a geometric framework linking the local structure of electronic bands and Fermi surfaces to intrinsic spin transport, demonstrating how hyperbolic regions generate spin currents and how spin operators relate to the exterior algebra of momentum space.
This study demonstrates that increasing cobalt content in Ti-rich NiCoCr-based superalloys significantly enhances coarsening resistance by elevating the activation energy, a phenomenon driven by cobalt-controlled interphase partitioning that increases multicomponent solute-transport resistance and reduces the apparent interfacial energy, despite a concurrent decrease in the solvus temperature.
Using synchrotron x-ray diffraction, researchers discovered that hexagonal close-packed water ice becomes the dominant phase over face-centered cubic ice in the superionic regime at high pressures and temperatures relevant to the interiors of Uranus and Neptune, likely due to a martensitic transition.
This paper demonstrates that using krypton sputtering enables the fabrication of high-performance, body-centered cubic tantalum films on silicon at temperatures as low as 200°C, thereby achieving state-of-the-art superconducting qubit quality factors while remaining compatible with standard semiconductor back-end-of-the-line processing.
Through explorative chemistry involving NbI, Li(CN), and LiO, researchers discovered and structurally characterized two new niobium oxyiodide cluster compounds, NbOI and NbOI, with the latter exhibiting a zero indirect band gap and 3D flat bands near the Fermi level due to its unique helical string-like structure and antiferrochiral packing.
This paper demonstrates that stacking topologically trivial layers under symmetry restrictions creates a parity-dependent topological phase transition where odd-layer configurations host symmetry-protected topological bound states in the continuum, a phenomenon experimentally verified in stacked acoustic lattices.
Using first-principles density functional theory calculations, this study demonstrates that graphyne and graphdiyne molecular wires self-assemble into energetically preferred non-aligned arrays on Au(111), Ag(111), and Al(111) surfaces via van der Waals interactions, retaining their semiconducting character to form promising one-dimensional metal-semiconductor heterostructures for molecular electronic devices.
This study demonstrates that depositing submonolayer transition metals on PbSnSe surfaces allows for the systematic tuning of Dirac and Rashba surface states, where polar (111) surfaces exhibit controllable Rashba splitting up to 3.5 eV·Å due to symmetry breaking and doping, while nonpolar (001) surfaces preserve inversion symmetry and instead show dephasing of double Dirac cones.
