This paper demonstrates the successful fabrication and characterization of high-performance neutron transmutation-doped germanium (NTD-Ge) cryogenic thermometers, which exhibit resistance behavior consistent with Mott's law down to 20 mK, thereby validating both the material's applicability for ultra-low temperature sensing and the reliability of the associated fabrication process.
Using real-time time-dependent density functional theory, this study predicts that intense ultrafast laser pulses can induce a persistent out-of-plane polarization in MoS/WSe heterobilayers through strong-field interlayer charge transfer, a process that can be further tuned by lattice strain for ultrafast optoelectronic applications.
This paper presents a data-driven approach that utilizes a neural network to accurately predict ion self-diffusivity in crystalline solids from short molecular dynamics trajectories by leveraging vibrational and structural fingerprints, thereby overcoming the computational expense of directly simulating slow diffusion processes.
This study demonstrates that a high-entropy kagome MnSn alloy with a specific rare-earth mixture exhibits distinct magnetotransport regimes and nonmonotonic magnetoresistance driven by competing rare-earth interactions that induce a broad anisotropy transition and incommensurate modulated spin structures.
This study demonstrates that the Wigner transport equation (WTE) framework, which accounts for both particle-like and wave-like coherence channels alongside higher-order phonon scattering, successfully predicts the ultralow thermal conductivity of strongly anharmonic materials like TlAgSe and CsPbIC, resolving the limitations of conventional Green-Kubo and Boltzmann transport theories.
This paper establishes the theoretical foundation for analyzing local spin dynamics in magnetic materials by deriving and validating the dynamic magnetic pair-density function (DymPDF) for a one-dimensional Heisenberg ferromagnet, demonstrating its ability to capture energy-dependent spin correlations and magnon-mode transitions through analytical derivation and SpinW simulations.
This paper presents the implementation and validation of the Nudged Elastic Band method within the CRYSTAL code, enabling accurate characterization of transition states in both molecular and periodic systems using hybrid density functional theory.
This paper introduces a Unified Bonding Entropy Model that explains open-shell stabilization in Kekulé graphene nanoflakes through "Clar-number-invariant resonance-space expansion," demonstrating that increasing the number of accessible resonance configurations rather than the maximum Clar sextet count drives electron unpairing and correlates strongly with key electronic and structural properties.
This study demonstrates that spin-current density-functional theory (SCDFT) functionals, specifically NCMSCAN and LFNCBR89-NCCS, successfully recover the experimental spin texture of the noncollinear magnet NiS at a computational cost comparable to standard semi-local approximations, outperforming traditional spin-DFT extensions in capturing noncollinear physics.
First-principles calculations reveal that biaxial compression in the bilayer iridate SrIrO collapses the interlayer exchange channel and giant magnon gap, driving a strain-induced spin-flop transition from a collinear -axis antiferromagnetic state to an in-plane ordered phase via a mechanism governed by Hund's exchange.
