Below are the latest papers in condensed matter and materials science, organized by their most recent publication dates.
This study demonstrates that high concentrations of intrinsic antisite defects in the topological magnet MnBiTe displace the topological surface states deep into the crystal bulk, thereby suppressing the surface gap and resolving the long-standing discrepancy between experimental observations and theoretical predictions.
This paper introduces MACE-H, a highly efficient and generalizable equivariant graph neural network that combines high-body-order message passing with node-order expansion to accurately predict Kohn-Sham Hamiltonians and electronic properties for diverse materials, including 2D systems and bulk gold, with sub-meV precision.
Using first-principles GW-BSE calculations, this study reveals the microscopic structure and correlation-driven real-space characteristics of moiré excitons in generalized Wigner crystals within MoSe2/MoS2 heterostructures, proposing photocurrent tunneling microscopy as a method to probe these strongly correlated excited states.
This paper introduces Point Group Order Parameters (PGOPs) as a new set of metrics to directly quantify local point-group symmetry in complex particle systems, demonstrating their superior utility in detecting crystalline order compared to traditional bond-orientational parameters and providing their implementation in the open-source SPATULA software package.
This paper presents innovative implementations of the BerkeleyGW package on Frontier and Aurora exascale supercomputers, achieving unprecedented performance portability and scaling for quantum many-body GW calculations on systems with up to 17,574 atoms, thereby enabling high-accuracy predictive simulations for future quantum technologies.
This study addresses the issue of morphological non-uniformity in GaN micro-pyramids and platelets grown via MOCVD by identifying the limitations of one-step growth and demonstrating that a controlled multi-step strategy combining sequential growth and thermal treatment significantly enhances structural regularity for advanced optoelectronic applications.
This study provides the first *ab initio* confirmation that conventional electron-phonon coupling accurately predicts the superconducting transition temperature of the decagonal AlOs approximant, thereby validating the use of such crystals as proxies for quasicrystals and predicting enhanced superconductivity in related Al-Re and Al-Ir alloys.
This paper presents a low-cost, cleanroom-free microfluidic device fabricated via lamination and UV lithography that offers simultaneous X-ray and UV-visible transparency, enabling versatile synchrotron-based studies of photoinduced structural dynamics in liquid samples through techniques like SAXS and UV-visible spectroscopy.
This study demonstrates that applying small magnetic fields during the synthesis of various Cu-based antiferromagnets can induce structural changes and alter magnetic ground states, including a measurable decrease in the Néel temperature and strengthening of antiferromagnetic interactions in atacamite.
This study demonstrates that mixed-valence polyoxovanadate V cages exhibit a highly anisotropic, room-temperature magnetoelectric effect driven by the relocation of itinerant electrons, offering a promising pathway for electric-field-controlled spin manipulation in molecular spintronics and quantum computing.
