This paper introduces the ghost Gutzwiller variational embedding framework to bridge the gap between single-particle band theory and strong electronic correlations, enabling the efficient prediction of topological features in correlated materials and revealing novel phenomena such as topologically nontrivial Hubbard bands with distinct edge states.
This paper demonstrates that machine learning interatomic potentials, fine-tuned on routine atomic relaxation data from first-principles calculations, can efficiently and accurately predict electron-phonon coupling and optical lineshapes for defects in solids, overcoming the computational bottleneck of traditional methods while resolving fine spectral details like those of the T center in silicon.
This paper introduces a new class of chiral altermagnetic magnetoelectrics, identifying the metal-organic framework K[Co(HCOO)] as a promising platform where electric polarization can be dual-mode switched via Néel-vector reorientation and structural chirality to enable nonvolatile multifunctional spintronics.
This study demonstrates that targeted phonon excitation can reversibly modulate the thermal conductivity of bulk boron arsenide, revealing that while three-phonon interactions allow for bidirectional control, the inclusion of four-phonon scattering fundamentally shifts the effect toward significant, frequency-dependent suppression.
By integrating nano-, meso-, and macroscale deformation experiments, this study demonstrates that 0.5 wt% Nb doping in SrTiO3 suppresses room-temperature plasticity by hindering dislocation nucleation, multiplication, and mobility through Sr vacancy-mediated defect interactions, resulting in a ~50% increase in yield stress.
This paper resolves the Marcus-Rehm-Weller paradox by demonstrating that both the predicted rate decrease and the observed saturation in electron transfer are opposite physical limits of a single two-level quantum Hamiltonian, with the outcome determined by whether the system operates in the nonadiabatic or adiabatic regime.
By combining DFT+ with exact diagonalization of the Anderson impurity model to account for Ce–Ce valence fluctuations, this study successfully reproduces the experimental magnetic moment and uniaxial anisotropy of the CeCo ferromagnet, demonstrating the critical role of dynamical correlations in designing high-performance permanent magnets.
This study combines XMCD experiments with theoretical calculations to characterize the electronic and magnetic properties of light rare-earth cubic Laves compounds, revealing crystal field suppression of rare-earth moments, a finite magnetic moment on Ni, and a tunable mixed-valent ground state in Ce that can be controlled via composition.
This paper reports the spontaneous emergence of a stable, equilibrium gas of negative trions at the surface of the layered semiconductor Ta2NiS5, revealed by angle-resolved photoemission spectroscopy as a unique interaction-driven surface state stabilized by band bending and quasi-one-dimensional geometry.
This paper introduces a configuration-space framework that overcomes the limitations of finite-size numerics to predict and explain the hierarchical energy gaps in quasicrystalline potentials as arising from resonant hybridization between distant sites, a theory validated by large-scale tight-binding simulations.
