This paper presents an exact formulation and perturbative expansion of the total energy beyond the Born-Oppenheimer approximation, clarifying the distinct nature of the electron-phonon contribution and demonstrating its small but non-negligible impact on the stability of diamond polymorphs.
This study utilizes first-principles molecular dynamics and thermodynamic modeling to demonstrate that chemical ordering in iron-silicon alloys under inner-core conditions governs phase stability, elastic anisotropy, and thermal conductivity, suggesting that metastable disordered cubic Fe-Si phases could explain key seismic and transport anomalies in Earth's inner core.
Using frequency- and time-domain THz spectroscopy, researchers identified a magnon mode in bulk -MnTe at low temperatures and, by comparing experimental results with a simplified antiferromagnetic resonance model, extracted an out-of-plane single-ion magnetic anisotropy of eV.
This paper presents an end-to-end framework that leverages quantum simulation to screen strongly correlated oxygen-electrode materials for solid oxide cells, bridging microscopic quantum observables with macroscopic engineering metrics to quantify the potential business value of improved electrode performance.
This study elucidates the structure-function relationships in polypseudorotaxane gels by combining targeted synthetic perturbations with molecular dynamics simulations to demonstrate how modulating polymer-cyclodextrin and cyclodextrin-cyclodextrin interactions governs network stability and mechanical toughness, thereby guiding the rational design of enhanced slide-ring gels.
This study demonstrates that Mn-deficient Ni-Mn-Ga oligocrystals with composition gradients serve as an effective platform for revealing that martensitic and premartensitic transformations abruptly disappear below a critical electron concentration threshold () while saturation magnetization increases with Mn content up to 25.8 at.%.
This study utilizes 3D diffraction-contrast tomography to demonstrate that in AA5252 aluminum alloy, the emergence and persistence of abnormal grain growth are primarily driven by crystallographic misorientation and the consumption of smaller neighboring grains with high-angle boundaries, rather than by local variations in second-phase particle density.
This paper reviews the century-old Bridgman formula, which links liquid thermal conductivity to sound velocity via phonons, highlighting its overlooked empirical success, theoretical foundations in hydrodynamics, and implications for resolving paradoxes in heat transport across the quantum-classical crossover.
This study reveals that the distinct optical properties of bulk PtSe and PtTe, particularly the significantly stronger Drude spectral weight and mid-infrared absorption in PtTe, arise from the higher energy position of chalcogen- states which enhances band overlap and facilitates transitions to Pt- bands, while the type-II Dirac points remain too deep to contribute appreciably to the interband conductivity.
This paper challenges the traditional donor-acceptor recombination model for several optical bands in diamond, arguing instead that internal transitions at specific defect centers, such as nearest-neighbor boron-nitrogen pairs, provide a more consistent explanation for the observed phenomena.
