Below are the latest papers in condensed matter and materials science, organized by their most recent publication dates.
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.
By employing DFT calculations and symmetry analysis on CrSb and related models, this study reveals that reducing six-fold to two-fold rotational symmetry via vacancy engineering, doping, or strain induces band-specific fragmented nodal curves and enables tunable anomalous Hall conductivity, thereby expanding the potential of altermagnets for future quantum devices.
This study demonstrates that applying an external magnetic field near the hard axis of an epitaxial iron film induces thresholdless nonlinear magnetization dynamics, including anharmonicity and harmonic generation, by exploiting the asymmetry in the magnetic energy potential to advance the design of controlled magnonic devices.
This paper demonstrates that structural relaxation in twisted bilayer BiSb creates a tunable moiré topological phase featuring coexisting trivial and nontrivial domains with protected gapless edge states that can be reversibly reconfigured by an out-of-plane electric field.
This paper benchmarks perturbative quantum master equation and mixed quantum-classical methods against fully quantum dynamics for hot exciton cooling in CdSe nanocrystals, revealing that while the former captures ultrafast diabatic mixing, the mapping approach to surface hopping (MASH) provides the most consistent agreement across all relaxation regimes.
This study resolves the long-standing mystery of flow thickening in polymer solutions by demonstrating that, in ordered porous media, the phenomenon is quantitatively governed by polymer extension at stagnation points, a mechanism distinct from the unsteady flow fluctuations dominant in disordered media.
This study employs a combined DFT and kMC approach to demonstrate that vacancies significantly reduce hydrogen mobility and increase activation energy in BCC Fe and Cr, with a more pronounced trapping effect observed in Cr due to stronger hydrogen-vacancy interactions.
