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 ...

Neural‐Network Potential for Defect Formation Induced by Knock‐On Irradiation Damage in 4H‐SiC
Advanced Electronic Materials, EarlyView.This study constructed an efficient neural network potential (NNP) for simulating the irradiation damage in 4H‐SiC with accuracy at first‐principles level. Using this NNP, the directional dependence of the threshold displacement energies (TDE) is determined based on high‐throughput calculations, and the calculated minimal TDE agrees with experiments ...

Quantum Transport in SnTe Nanowire Devices
Advanced Electronic Materials, EarlyView.A variety of quantum transport experiments are observed in SnTe nanowire devices and attributed to microscopic differences in the fabrication. Three categories can be distinguished: semiconducting behavior, partial superconductivity and Fabry‐Pérot oscillations.

Advanced Electronic Materials, EarlyView.The use of air stable but thermally labile molecules provides an efficient strategy for the N‐type doping of organic semiconductors with relatively low electron affinities. Design criteria for efficient dopants should also take into account diffusion and phase segregation that cannot be decoupled from thermally activated doping.

Advanced Energy Materials, EarlyView.A Ru8%‐Co3O4 catalyst containing Ru single atoms (SAs) exhibits exceptional oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) performance in acidic, neutral, and alkaline media. When used as the anode and cathode catalysts in an anion exchange membrane water electrolyzer (AEMWE) device, a low cell voltage of just 2.06 V is needed to

Advanced Energy and Sustainability Research, EarlyView.An aqueous potassium‐ion battery using vanadium hexacyanoferrate (VHCF) as the cathode and graphite as the anode is presented. During charge/discharge, K+ ions shuttle between electrodes through the electrolyte, enabling energy storage. The VHCF material demonstrates high capacity (≈121 mAh g−1), fast kinetics, and eco‐friendliness, making it a ...
