Condensed matter physics and materials science form a dynamic partnership, exploring how the collective behavior of atoms gives rise to the unique properties of solids and liquids. This field bridges the gap between fundamental quantum mechanics and the practical engineering of everything from flexible electronics to superconductors, turning abstract theories into tangible innovations that shape our daily lives.

Below are the latest papers in condensed matter and materials science, organized by their most recent publication dates.
This paper establishes that the in-plane Burgers-vector direction of threading edge dislocations in GaN can be nondestructively determined using phase-contrast microscopy by analyzing the specific arrangement of bright and dark contrast, a finding validated by X-ray topography and electron microscopy techniques.
This paper argues that reliable AI/ML discovery of magnetic materials requires hierarchical workflows and databases that incorporate physical completeness and kinetic synthesizability criteria, such as a new synthesis-window descriptor, rather than relying solely on the volume of calculated structures.
This paper proposes a microscopic mechanism where the competition between forward-confined polar-optical-phonon emission and elastic alloy scattering synchronizes ionization events into a dynamic staircase, thereby explaining the experimentally observed sub-McIntyre avalanche noise in Sb-based alloys and HgCdTe.
This study demonstrates that varying the source-to-substrate distance during thermal evaporation effectively modifies the structural, optical, and electrical properties of thermally deposited CdTe, CdSe, and SbS thin films, identifying CdTe and CdSe as promising absorber materials for thin-film solar cells due to their suitable band gaps and high absorption coefficients.
Using two-dimensional phase-field simulations, this study reveals how the competition between wetting kinetics and spinodal decomposition in ternary to quinary mixtures drives complex morphological evolution around filler particles, ultimately demonstrating that increasing component numbers slows domain coarsening while wetting accelerates it, offering new avenues for controlling microstructures in multicomponent systems.
This paper presents a unified theory of magic angles in twisted bilayer graphene within a chiral continuum model, demonstrating that the phenomenon arises from a non-Abelian pseudo-magnetic field which generates an asymptotic sequence of flat bands, distinct topological phases, and a specific scaling rule for higher-order magic angles.
This study demonstrates that the electrical performance of amorphous InGaZnO thin-film transistors is rigidly controlled by shallow trap states, specifically a Ga-Ga-In oxygen vacancy defect located ~0.32 eV below the conduction band, which can be accurately quantified and simulated using ultrabroadband photoconduction microscopy and DFT+U calculations.
This first-principles multiscale computational study demonstrates that a ferrocene-functionalized covalent organic framework (MSUCOF-4-FeCp) significantly exceeds U.S. Department of Energy hydrogen storage targets by achieving 18.0 wt% gravimetric and 72.6 g H2/L volumetric capacities at 298 K and 700 bar through optimal binding energies, offering a cost-effective alternative to precious metal-based materials.
By modulating the chemical bath deposition growth mechanism with citrate ligand additives to reduce grain boundary density and deep trap concentrations, researchers successfully surpassed the 800 mV open-circuit voltage barrier in antimony sulfide photovoltaics to achieve a record 824 mV, demonstrating that defect engineering rather than intrinsic self-trapping limits device performance.
This study investigates the microstructural and magnetic evolution of Ni-Mn-Sn Heusler alloys processed via direct energy deposition, demonstrating that while post-heat treatment restores a sharp martensitic transformation, significant manganese evaporation and oxidation during printing necessitate strict control over composition and oxygen levels to maintain optimal magnetic properties for solid-state cooling applications.
