This paper presents a rigorously validated high-dimensional neural network potential trained on DFT data that accurately captures the subtle energetics and anisotropic deformation mechanisms of NiTi martensite, enabling robust finite-temperature molecular dynamics simulations of large-scale systems over nanosecond time scales.
This paper presents an efficient, GPU-accelerated plane-wave implementation of analytical nuclear forces within the Bethe-Salpeter equation framework, enabling scalable excited-state relaxation studies for large solid-state systems and demonstrating its ability to correct semilocal TDDFT errors in defect environments like hexagonal boron nitride.
This paper introduces a phonon-interpolation method that combines localized ab initio calculations with dense -point grid sampling to accurately compute electron-phonon spectral functions and optical lineshapes for defects in wide-band-gap semiconductors, overcoming the resolution limits of standard supercell approaches as demonstrated on the nitrogen-vacancy center in diamond.
This study demonstrates that the ferroelectric semiconductor ErMnO can function as an energy-efficient physical reservoir for temporal information processing by utilizing its photo-induced currents and controllable relaxation dynamics to significantly improve the recognition accuracy of time-varying light pulses.
This study achieves the complete quantitative determination of the energies and relative Raman tensor elements for all 15 Raman-active modes in monoclinic -GaO by combining polarization angle-resolved Raman spectroscopy on multiple crystal planes with a novel fitting procedure that explicitly accounts for the material's birefringence.
Using scanning tunneling microscopy/spectroscopy combined with ab initio simulations, this study identifies a b-axis-aligned double sulfur vacancy as a common intrinsic defect in CrSBr and characterizes its structural and electronic signatures near the valence band edge.
This study demonstrates that in superconducting NbSe2, Meissner currents induced by an in-plane magnetic field selectively Doppler-shift Bogoliubov quasiparticle spectra at charge density wave vectors, thereby driving a symmetry-breaking transition in CDW modulations and enabling momentum-space engineering of intertwined electronic phases.
This paper theoretically demonstrates that the coexistence of a real bond modulation and a chiral flux phase in a square-lattice superconductor breaks time-reversal symmetry to drive the system into topologically nontrivial phases with Chern numbers of , which are experimentally detectable via quantized thermal Hall conductivity.
Using first-principles DFT+U+J computations, this study demonstrates that the optical properties of hematite (-FeO) are governed by polaronic transitions involving electron localization on adjacent iron atoms coupled to specific longitudinal optical phonons, thereby accurately reproducing the material's temperature-dependent dielectric function and Raman spectra.
This study employs molecular dynamics simulations and machine learning to reveal that the thermal amorphization of ZIF-4 and melting of ZIF-zni proceed via distinct two-step mechanisms involving connectivity changes around Zn centers, with ZIF-4's non-isotropic amorphization driven by density and bond lability.
