Chaos near to the critical point: butterfly effect and pole-skipping
European Physical Journal C: Particles and FieldsWe study the butterfly effect and pole-skipping phenomenon for the 1RCBH model which enjoys a critical point in its phase diagram. Using the holographic idea, we compute the butterfly velocity and interestingly find that this velocity can probe the ...

Elucidating Sodium Ion Storage Mechanisms in Hard Carbon Anodes at the Electronic Level
Advanced Functional Materials, EarlyView.High‐resolution, multi‐frequency continuous wave, and pulsed Electron Paramagnetic Resonance (EPR) spectroscopy uncover the intricate Na ion storage mechanisms in hard carbon. This study reveals the coexistence of Na ion intercalation and solvent co‐intercalation, alongside a subsequent transition of Na ions from ionic to quasi‐metallic to metallic ...

Near‐Infrared Circularly Polarized Electroluminescence with Switchable Handedness in Organic LEDs
Advanced Functional Materials, EarlyView.The first fully‐organic circularly polarized near‐infrared OLED, using a co‐assembled active layer of ITIC and a chiral inducer, exhibits dissymmetry values up to 0.074 and 1.65 Wsr−1m−2 radiance. The circular polarization sign can be switched by manipulating the position of the recombination zone, resulting in enhanced device performance and stability.

Gate‐Tunable Hole Transport in In‐Plane Ge Nanowires by V‐Groove Confined Selective Epitaxy
Advanced Functional Materials, EarlyView.Ge nanowires are promising for hole spin‐based quantum processors, requiring direct integration onto Si wafers. This work introduces V‐groove‐confined selective epitaxy for in‐plane nanowire growth on Si. Structural and low‐temperature transport measurements confirm their high crystalline quality, gate‐tunable hole densities, and mobility.
