Below are the latest papers in condensed matter and materials science, organized by their most recent publication dates.
This paper introduces a configuration-space framework that overcomes the limitations of finite-size numerics to predict and explain the hierarchical energy gaps in quasicrystalline potentials as arising from resonant hybridization between distant sites, a theory validated by large-scale tight-binding simulations.
The paper introduces "Fermi Sets," a universal and interpretable neural architecture that approximates fermionic wavefunctions using a provably small number of antisymmetric basis functions multiplied by symmetric factors, achieving superior accuracy over diffusion Monte Carlo benchmarks for metallic solid hydrogen while maintaining minimal computational overhead.
This paper introduces a scalable, unsupervised clustering framework that efficiently segments and compresses 4D-STEM and 5D-STEM data by identifying crystallographically distinct domains through local diffraction-pattern similarity, thereby enabling rapid and accurate structural mapping as demonstrated on in situ gold nanoparticle growth.
This paper reports the successful fabrication and characterization of a Zr-based bulk metallic glass clamp cell that offers superior neutron transmission and a clean background profile compared to conventional CuBe cells, thereby significantly enhancing high-pressure inelastic neutron scattering measurements.
This paper introduces a novel ultrafast spectroscopy platform capable of simultaneous high pressure (up to 40 GPa) and high magnetic field (up to 7 T) to investigate the trilayer nickelate , revealing that while pressure suppresses charge-density-wave order and induces incipient superconducting correlations, the lack of magnetic field dependence suggests any resulting superconducting state is non-bulk and inhomogeneous rather than a true bulk phase.
This paper demonstrates the first excitation of the thorium-229 nuclear transition using a continuous-wave laser in absorption mode, a breakthrough that enables fast signal acquisition for solid-state nuclear clocks and reveals a highly symmetric crystal center with minimal electric field gradients.
Researchers have identified and characterized two new metastable molecular nitrogen phases, -N and -N, near megabar pressures using diamond anvil cell experiments, single-crystal X-ray diffraction, and theoretical calculations.
This paper introduces a method combining multi-harmonic nonlinear polarimetry with the Maximum Entropy Method to reconstruct full molecular orientation distributions in organic thin films without prior assumptions, thereby revealing complex features like asymmetry and bimodality that are invisible to conventional techniques and exposing limitations in current molecular dynamics simulations.
This study elucidates the distinct and synergistic roles of anisotropic crack density and anisotropic strain energy in phase-field modeling of mixed-mode fracture, demonstrating that while crack density primarily governs the fracture path and resistance, anisotropic strain energy controls the driving force and significantly influences elastic stiffness and peak load in stress-concentration geometries.
This study combines DFT+DMFT calculations with spectroscopic data to demonstrate that UCd is a highly localized 5 antiferromagnet, challenging the conventional interpretation that the absence of satellite features in photoemission spectra necessarily indicates itinerant 5 behavior.
