Below are the latest papers in condensed matter and materials science, organized by their most recent publication dates.
This study reveals that domestic cat hairs are not uniform fibers but functionally graded composites, where variations in layered keratin walls, melanosome-like granules, and calcium enrichment along the hair's length create a structure-function relationship that correlates with local mechanical properties.
This study reports the direct optical observation of electrically driven trion drift at high velocities, which unexpectedly induces a counter-directional flow in coexisting neutral excitons, revealing a novel interaction-driven regime of counterpropagating exciton-trion transport.
The paper presents SAGE-Net, a novel multimodal framework that integrates crystallographic semantics directly into geometric message passing via a Semantic-Guided Message Passing (SGMP) mechanism, achieving state-of-the-art performance in predicting diverse material properties and synthesizability while ensuring physical interpretability.
This study demonstrates that inserting a thin tantalum buffer layer between the silicon substrate and a tantalum nitride seed layer significantly enhances the internal quality factor of superconducting resonators by suppressing nitrogen accumulation and structural disorder at the interface, thereby reducing two-level system losses.
This paper introduces ultra-transient grating spectroscopy (UTGS), a novel application of transient grating techniques that captures early-time thermoacoustic phenomena to directly visualize the frequency-domain angular-resolved Green's function of surface acoustic waves, enabling detailed, contactless characterization of elastic anisotropy in single-crystalline and nanostructured materials.
This paper introduces event-sparse stack denoising for 4D-STEM, a method that leverages time-resolved electron event data and sparsity-based algorithms to achieve comparable image quality at significantly reduced electron doses while enhancing defect detection sensitivity and enabling critical dose estimation.
This paper demonstrates that optimizing the defect density and interfaces of piezoelectric films in high-overtone bulk acoustic-wave resonators enables phonon lifetimes up to 400 μs and a record-high quantum coherence cooperativity of when coupled to superconducting qubits, establishing a new milestone for circuit quantum acoustodynamics devices.
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.
