Observation of Room-temperature Charge Density Wave Correlations via Coherent Phonon Spectroscopy in Sn-doped Kagome Superconductor CsV $_3$ Sb $_5$

Using ultrafast time-resolved reflectivity and synchrotron X-ray diffraction, this study reveals that Sn doping introduces quenched disorder that pins short-range charge density wave correlations in the Kagome superconductor CsV $_3$ Sb $_5$ , allowing these correlations to persist robustly up to room temperature well beyond the long-range order phase boundary.

Extended Mean-Field Theory for the 2D Hubbard Model in Degenerate Dilute Electron Gases: Fluctuations, Superconducting Dome, and Interaction Mechanisms in Strontium Titanate

This paper presents an extended mean-field theory for the 2D Hubbard model in strontium titanate that successfully reproduces the experimental superconducting dome, elucidates the competition between charge-density-wave and superconducting orders, and provides criteria to distinguish electron-electron from electron-phonon interaction mechanisms in dilute electron gases.

Achieving Robust Extrapolation in Materials Property Prediction via Decoupled Transfer Learning

This paper demonstrates that decoupled transfer learning, which separates pretrained graph neural network feature extractors from simple regressors, significantly outperforms end-to-end training in extrapolating materials properties by leveraging transferable structural knowledge to maintain learned trends beyond training distributions.

Second-Coordination-Sphere Cation Substitution as a Tool for Controlling Phase Transitions and Performance of the Luminescence Thermometry

This study demonstrates that substituting Li+ with Na+ in the second coordination sphere of Eu3+ in LiYO2 effectively shifts the phase transition temperature to optimize the operating range of luminescent thermometers, albeit at the cost of reduced relative sensitivity due to weakened first-order transition characteristics.

Martensitic laminate geometry controls electronic phase transitions in a Mott insulator

This study demonstrates that in epitaxial V2O3 thin films, the metal-insulator transition temperature is directly controlled by the degree to which martensitic laminate geometries satisfy macroscopic strain compatibility, revealing that finely tuned layered mixtures of twin variants govern electronic phase transitions.

A stochastic simulation of the dislocation-mediated etching of porous GaN distributed Bragg reflectors

This paper presents a stochastic simulation model that successfully reproduces the complex "cascade" pore morphologies and chronoamperometry trends observed during the dislocation-mediated electrochemical etching of porous GaN distributed Bragg reflectors by correlating etching probabilities with applied bias.

Revealing Rotational Symmetry Breaking Charge-density Wave Order in Kagome Superconductor (Rb, K)V $_3$ Sb $_5$ by Ultrafast Pump-probe Experiments

By combining ultrafast reflectivity experiments and density functional theory calculations, this study reveals that the charge density wave order in the Kagome lattice superconductors RbV $_3$ Sb $_5$ and KV $_3$ Sb $_5$ corresponds to a shifted 2×2×2 inverted star pattern, thereby breaking the six-fold rotational symmetry.

High-throughput development of flexible amorphous materials showing large anomalous Nernst effect via automatic annealing and thermoelectric imaging

This study employs a high-throughput methodology combining automated annealing and lock-in thermography to screen 151 flexible Fe-based alloy ribbons, identifying seven candidates with record-breaking anomalous Nernst coefficients and revealing that short-range atomic order in the amorphous matrix, rather than specific nanoclusters, drives the enhanced thermoelectric performance near the first crystallization temperature.
