Below are the latest papers in condensed matter and materials science, organized by their most recent publication dates.
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.
This paper investigates topological magnons on an anisotropic square-hexagon-octagon lattice derived from a biphenylene network, proposing a DMI-free mechanism for type-II Dirac points and Dirac nodal loops characterized by invariants, while analyzing their topological phase transitions, chiral edge modes, and associated thermal Hall and Einstein-de Haas effects.
This paper presents a defocus phase retrieval method that successfully reconstructs the optical point-spread function of an uncorrected scanning electron microscope by analyzing a focal series of images from gold nanoparticles, thereby enabling experimental aberration quantification at 20 keV.
This paper proposes bicircular Raman spectroscopy as a universal optical probe to identify altermagnetic magnons by detecting their momentum-dependent chirality and enhanced nonlinear light-magnon interactions, thereby distinguishing altermagnets from antiferromagnets regardless of the underlying magnon topology.
This paper presents an efficient, fully ab-initio method combining Monte Carlo integration, interpolation, and long-wavelength extrapolation to accurately and rapidly calculate GW corrections for 3D and 2D metals by correctly accounting for intraband transitions, thereby achieving excellent agreement with experimental ARPES data for materials like doped MoS and graphene.
