Scrambling‐Enhanced Quantum Battery Charging in Black Hole Analogues
Advanced Science, EarlyView.By employing a black‐hole‐analog quantum battery constructed from a position‐dependent XY model, its dynamical behavior is investigated through a quench of the scrambling parameter. It is systematically quantified that how the simulated scrambling improves key performance metrics‐namely, stored energy, peak power, and charging time‐thereby offering a ...

Transmission of Radio‐Frequency Waves and Nuclear Magnetic Resonance in Lanthanum Superhydrides
Advanced Science, EarlyView.1H NMR and radio‐frequency transmission measurements of lanthanum superhydrides at 165 GPa reveals a transition at 260–280 K by a strong suppression of the signal intensity, significant changes in NMR spectra, including a dramatic decrease of the relaxation rate 1/T1T, and pronounced shielding effect, which may have a superconducting nature.

Support‐Intensified Ir─P/O─Mo Cooperative Linkages for Robust Acidic Water Dissociation
Advanced Science, EarlyView.An electrocatalyst with the coexisting Ir‐O‐Mo and Ir‐P‐Mo linkages is rationally synthesized for achieving exceptional bifunctional performance in acid solution. Abstract The efficient production of hydrogen via acidic water electrolysis is hampered by the sluggish kinetics of the oxygen evolution reaction (OER) and the scarcity of robust bifunctional

Advanced Science, EarlyView.MnRhP has been identified as a novel kagomé magnet that hosts magnetic skyrmions above room temperature and exhibits a large intrinsic anomalous Hall effect. The latter originates from Berry curvature associated with gapped nodal lines, establishing MnRhP as a promising platform for exploring high‐temperature topological phenomena in both real and ...

Spectroscopic Evidence of Edge‐Localized States in an Antiferromagnet Topological Insulator NdBi
Advanced Science, EarlyView.Using spin‐polarized scanning tunneling microscopy (STM) in conjunction with quasiparticle interference, we successfully identify distinct signatures of the ferromagnetic and antiferromagnetic terminations in NdBi, a rare‐earth monopnictide exhibiting non‐trivial topology and magnetism. We demonstrate that step edges on ferromagnetic surfaces host well‐

Novel microstrip transformer for superconducting microelectronics
Electronics Letters, 1987 A novel monolithic impedance transformer based on super-conducting microstrip has been constructed and tested. The transformer contacts devices on the substrate surface via an evaporated ground plane. Bandwidths of 25% at an impedance transformation of 50 : 0.5Ω was achieved at 9 GHz.

Advanced Science, EarlyView.We combine altermagnet with topological insulators and subject the structure to Floquet driving. This breaks time‐reversal symmetry and creates a new type of higher‐order topological insulator. Its key feature is the emergence of programmable “0/π‐corner modes” that can be controlled by magnetic field direction, offering a novel dynamic platform for ...
