This paper presents a first-principles formalism based on Koopmans-compliant hybrid functionals to calculate polaron self-trapping rates across a wide range of technologically relevant materials, revealing lifetimes spanning seven orders of magnitude and offering critical insights into carrier localization dynamics, including the potential hindrance of -type conductivity in rutile GeO.
By combining Sb NQR measurements and density functional theory calculations, this study reveals that Sn substitution in CsVSb induces local structural distortions and drives a complex interplay between these impurity effects and competing lattice instabilities, ultimately stabilizing nearly degenerate V-trimer structures in the fully doped limit.
SALTED is an open-source Python package that employs a symmetry-adapted Gaussian process regression algorithm to efficiently predict quantum-mechanical electron densities and their electric field responses in molecular and condensed-phase systems, leveraging a linear atom-centered decomposition for high transferability and seamless integration with major electronic-structure codes.
This paper utilizes self-consistent relaxation theory to define the Frenkel line in Yukawa fluids as the thermodynamic boundary where the roton minimum in the longitudinal excitation dispersion relation vanishes, demonstrating that this dynamic crossover can be directly determined from the static structure factor and aligns with molecular dynamics simulation results.
This DFT+U study reveals that Gd/W co-doping in La2Mo2O9 induces a massive Gd-4f exchange splitting and significantly enhances Mo-4d crystal-field splitting, providing a microscopic electronic explanation for the observed lattice contraction, Raman mode softening, and the suppression of oxide-ion conductivity in this solid oxide fuel cell material.
This study demonstrates that controlled NaOH treatment of natural biotite nanosheets induces an insulator-to-semiconductor transition through ion exchange and defect engineering, transforming the abundant mineral into a tunable 2D material with reduced bandgap and promising optoelectronic properties.
This study reveals that exciton multipolarity in van der Waals heterostructures serves as a design principle for controlling photoinduced interlayer breathing modes, where dipolar excitons generate coherent phonons while quadrupolar excitons produce squeezed states, with the ability to switch between these regimes via an external electric field.
By combining density-functional theory calculations with far-infrared measurements to correct the harmonic approximation's failure in capturing soft-mode frequencies, this study experimentally constrained modeling of the Pockels response in KNbO3 and KTN, revealing KTN's superior electro-optic potential as a low-energy alternative to standard technologies.
This paper presents a hierarchical autonomous experimentation framework for scanning probe microscopy that synergistically combines agentic AI for high-level scientific reasoning and strategy selection with deterministic algorithms for precise, reliable physical execution and quantitative analysis.
This study employs high-throughput combinatorial thin-film synthesis and multimodal characterization to map the structure-property relationships of (Gd/Ho/Er/Dy)2Zr2O7 ceramics, revealing that the largest experimentally observed lattice parameter, rather than cation size disorder or equiatomic composition, correlates with a pronounced minimum in thermal conductivity.
