Below are the latest papers in condensed matter and materials science, organized by their most recent publication dates.
This paper demonstrates through theoretical analysis and experimental observation that the non-homogeneous distribution of atoms in complex concentrated alloys reduces overall system energy by compensating for tensile and compressive strain fields, thereby highlighting the critical role of local chemical and structural heterogeneity in determining thermodynamic stability.
This paper demonstrates that solid-electrolyte interphase (SEI) growth across most lithium-battery anode chemistries follows a universal parabolic law with a diffusion-limited exponent of 1/2, while anode-free configurations uniquely deviate with a super-parabolic exponent of approximately 0.77 due to nucleation-controlled kinetics.
This paper proposes a minimal nonlinear ODE model demonstrating that a saddle-node bifurcation in interfacial morphology governs battery degradation, successfully mapping various anode configurations onto a stability spectrum where anode-free lithium sits near the critical threshold, thereby predicting universal instability and validating key experimental trends.
This paper demonstrates that thermally induced curvature in hexagonal boron nitride (hBN) flakes creates strain gradients that suppress phonon coupling, thereby significantly enhancing the room-temperature spectral purity and coherence of embedded single-photon emitters.
This paper introduces QT-Net, a rotationally augmented graph neural network evaluated via a principled out-of-distribution protocol based on SOAP descriptors, which demonstrates that inferring atomic properties like electron populations and multipoles improves downstream molecular property prediction and accurately recovers ground-truth dipole moments.
This study establishes the noncentrosymmetric rare-earth germanides RGaGe (R = Ce, Pr, Nd) as a tunable platform for exploring the evolution from d- to f-orbital dominated topology and demonstrates their giant intrinsic anomalous Hall effect driven by robust Weyl semimetallic states coupled with magnetic order.
This study employs machine learning enhanced by generative adversarial network-based data augmentation to successfully predict body-centered cubic phase stability in cobalt-free high-entropy alloys, identifying mixing enthalpy and atomic size difference as key descriptors with 84% accuracy.
This paper challenges the conventional use of single oxygen vacancy formation energy for screening perovskite thermochemical materials by demonstrating that accounting for finite vacancy concentrations and configurational entropy in doped CaMnO3 provides a more accurate, experimentally consistent framework for predicting equilibrium oxygen stoichiometry and guiding high-throughput material discovery.
Using first-principles calculations and Monte Carlo exploration, this study elucidates the atomic-scale structure of Eu in -SiAlON phosphors, confirming a planar Eu-N coordination model that explains the material's weak electron-phonon coupling, resolved vibronic peaks, and the red-shift of emission with increasing Al/O concentration.
This study resolves the long-standing puzzle of the sign reversal in the temperature dependence of the bandgap in CsPb(Br,Cl)3 nanocrystals by demonstrating that the inversion, occurring at chlorine concentrations above 40%, is driven solely by a unique electron-phonon coupling mechanism involving synchronous octahedral tilting and cesium rattling.
