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.
At Gist.Science, we process every new preprint in this category directly from arXiv to make these complex discoveries accessible to everyone. Our team generates both plain-language overviews and detailed technical summaries for each paper, ensuring that researchers, students, and curious minds alike can grasp the latest breakthroughs without getting lost in dense jargon.
Below are the latest papers in condensed matter and materials science, organized by their most recent publication dates.
This study reveals that in the pnictogen-based chalcohalide BiSBr, vacancies introduced during synthesis or post-treatment induce extrinsic carrier localization through the formation of defect-bound hot polarons, which divert excited carriers from cooling to the band edge and thereby limit solar absorber efficiency.
This paper presents a synergistic framework combining coarse-grained simulations, experimental rheology, and machine learning to efficiently map the design space of DNA-based soft matter fluids, enabling the rational and accelerated discovery of materials with tailored bulk rheological properties.
This study employs a two-level machine learning strategy combining graph neural network potentials and direct energy predictors to map the thermodynamic stability of (Cs/FA)Pb(Br/I)₃ and (Cs/FA)Sn(Br/I)₃ perovskite alloys, revealing that Sn-based systems have narrower stable composition regions than Pb-based ones and that maximum stability occurs at high iodine content.
This paper proposes and theoretically demonstrates that magnetic precession near the equilibrium axis in collinear antiferromagnetic semiconductors can generate both uniform and staggered spin polarizations without requiring heterojunctions, with these responses being controllable via electric gate fields and Floquet light-dressing.
This paper demonstrates that shape-memory alloy-polymer composite rods exhibit hysteretic acoustic band structures, where the stop-band edges and transmission spectra form closed loops in the temperature-frequency plane due to the material's thermal hysteresis, while the spectral hysteresis width can be further tuned by adjusting the geometric filling fraction.
This study reports the successful composition-dependent synthesis of layered ternary iron nitride thin films (FeWN₂ and FeMoN₂) via reactive sputtering and ammonia annealing, revealing distinct structural accommodation mechanisms and strong couplings between composition, microstructure, and electronic/magnetic properties that differ significantly between the tungsten and molybdenum systems.
This paper introduces an operator-level factorial benchmark that decomposes molecular MPNNs into distinct message-seed, fusion, and update components, revealing that message construction—particularly concatenation-based node-edge fusion—is the primary driver of performance, thereby providing targeted design heuristics that outperform monolithic architecture searches.
This study identifies FeSb2 as a molecular orbital Kondo insulator by using resonant inelastic X-ray scattering and first-principles calculations to demonstrate that hybridized Fe d-Sb p molecular orbitals create a mixed-configuration ground state with propagating collective modes, offering a new paradigm for engineering high-temperature Kondo many-body states.
This study utilizes area-selective angle-resolved photoemission spectroscopy to demonstrate that interlayer coupling in the 4Hb-TaS₂ superlattice drives the formation of chiral "windmill" Fermi surfaces, Kondo-like peaks, and distinct charge orders, thereby reconciling competing Kondo and Mott-Hubbard models to explain its emergent correlated electronic states.
This paper presents a unified theoretical framework describing how electromagnetic interactions with bulk materials and surfaces induce free-electron decoherence, identifying material-specific mechanisms like plasmons and band-gap excitations while demonstrating how the resulting temperature-dependent effects can be harnessed for nanoscale thermometry.
