Exceptional Antimodes in Multi‐Drive Cavity Magnonics
Driven‐dissipative cavity‐magnonics provides a flexible platform for engineering non‐Hermitian physics such as exceptional points. Here, using a four‐port, three‐mode system with controllable microwave interference, antimodes and coherent perfect extinction (CPE) are realized, enabling active tuning to antimode exceptional points.

SPICE‐Compatible Compact Modeling of Cuprate‐Based Memristors Across a Wide Temperature Range
A physics‐guided compact model for YBCO memristors is introduced, incorporating carrier trapping, field‐induced detrapping, and a differential balance equation to describe their switching dynamics. The model is compared with experiments and implemented in LTspice, allowing realistic circuit‐level simulations.

Controllable Ge Hut Wires With Mobilities Exceeding 20 000 cm2 V−1 s−1
The controlled growth of germanium hut wires on patterned SiGe/Si(001) substrates is reported. These self‐assembled nanowires achieve a record hole mobility of 22 900 cm2 V−1 s−1 at 4.2 K. Remarkably, conductance quantization is observed at a channel length of 1.9 µm, highlighting their exceptionally low disorder and paving the way for scalable, high ...
