Below are the latest papers in condensed matter and materials science, organized by their most recent publication dates.
This paper introduces SevenNet-Nano, a lightweight universal machine-learning interatomic potential that leverages knowledge distillation from a large foundation model to achieve high accuracy and transferability while significantly reducing computational costs for large-scale atomistic simulations.
This study demonstrates that while conventional GGA fails to predict the spin-density wave ground state of bcc chromium, various meta-GGA functionals exacerbate the issue by overestimating magnetic moments and destabilizing the SDW state, with the TPSS functional providing the most accurate description among those tested and highlighting the need for advanced non-local or hybrid functionals.
This paper introduces opt-DDAP, a reformulated density-derived atomic point charge method that leverages automatic differentiation to optimize Gaussian basis parameters and reciprocal-space cutoffs, thereby overcoming the numerical instability and reliance on fixed heuristics of the original approach to produce robust charges for long-range electrostatic modeling.
This paper establishes a purely electronic mechanism for the resonant light-enhanced pair correlations observed in KC, demonstrating through advanced numerical simulations that a symmetry-constrained two-photon pathway drives the system into a superconducting-like state, thereby confirming that the experimental 10 THz resonance stems from coherent pair formation rather than improved metallicity.
This study demonstrates that synthesizing Sn1-xInxTe via solid-state reaction and employing Rietveld refinement and Williamson-Hall analysis reveals that In doping substitutes Sn and introduces minor embedded phases, with the Sn0.96In0.04Te composition achieving the optimal balance of maximum host phase purity and highest thermoelectric power factor.
This paper presents the GPU acceleration of the Abinit code for plane-wave DFT calculations, detailing the algorithmic revisions and vendor library integrations required for multi-GPU scalability while comparing the performance of Locally Optimal Block Preconditioned Conjugate Gradient and Chebyshev polynomial filtering diagonalization methods on heterogeneous CPU-GPU architectures.
This study reveals that positive bias and high-temperature stress in amorphous IGZO TFTs induce a reversible negative threshold voltage shift caused by the broadening of conduction band tail states and increased hydrogen doping, rather than the generation of new dielectric traps.
Through self-flux synthesis, researchers discovered a new family of ladder-like alkali chromium tellurides (CrTe, where = Rb, Cs) that feature a unique hybrid crystal framework and exhibit distinct antiferromagnetic and ferrimagnetic ground states, demonstrating the effectiveness of flux growth for designing complex low-dimensional magnetic materials.
This study demonstrates that hydration-induced topological differences in secondary building units dictate the distinct high-pressure behaviors of Na2ZrSi2O7 and its hydrated analogue, where the anhydrous phase undergoes a phase transition and electronic gap shift via octahedral distortion, while the hydrated phase remains stable and retains a direct band gap through group tilting.
This study employs density functional theory, specifically the general gradient approximation (GGA), to demonstrate that all fifteen lanthanide monoxides (from La to Lu) are thermodynamically stable in the B1 (NaCl-type) structure at ambient pressure and undergo a pressure-induced phase transition to the B2 (CsCl-type) structure at elevated pressures.
