Quantum Thermalization Dynamics of Fermi Gases Quenched to the BEC‐BCS Crossover
Advanced Science, EarlyView.This study, reporting the first experimental realization of interaction quench far faster than the Fermi timescale in fermionic many‐body systems, explores real‐time quantum thermalization dynamics in the BEC‐BCS crossover. It observes prethermal states with distinct lifetimes after quantum quench, uncovers universal prethermal scaling, and observes ...

Metallic Bond Induces Soft Phonon Mode and Anharmonicity in Heusler Alloy
Advanced Science, EarlyView.The fruitful functional performances of metastable Heusler alloys originate from the martensitic transformation driven by the transverse acoustic soft phonon mode, regulated by anharmonicity. This study reveals that the long‐range interaction rooted in metallic bonding between spin‐down d‐orbitals of Ni─Ni induces phonon softening and significant ...

Magnetic Precursor to the Structural Phase Transition in V2O3
Advanced Electronic Materials, EarlyView.V₂O₃, a model Mott insulator, undergoes a metal‐insulator transition linked to structural and magnetic transitions, though the underlying mechanism remains unclear. Through muon‐spin rotation and X‐ray diffraction on strain‐engineered thin films, a magnetic precursor to the structural transition is identified, emphasizing the key role of magnetism in ...

Advanced Electronic Materials, EarlyView.This work focuses on the crystallization dynamics in lead iodide perovskite films: In situ UV absorption spectroscopy reveals a PbI2‐DMF solvated (PDS) phase before nucleation, influencing perovskite formation. PDS clusters act as nucleation seeds, linking precursor solution concentration to crystallization.

Ultra‐High‐Capacity of Earth‐Abundant Cathodes Enabled by Excess Fluoride‐Ion Insertion/Extraction
Advanced Energy Materials, EarlyView.A perovskite oxyfluoride SrFeO2Fx can accomodate excess F– beyond x = 1 in the structure with oxygen redox (O–O bond formation). The Sr‐substituted CaFeO2Fx (Ca0.8Sr0.2FeO2Fx) provides an extremely large capacity of 580 mAh g−1 (2595 mAh cm−3). This research will provide new design principles for the development of all‐solid‐state fluoride‐ion battery ...
