A team led by Professor Zhang Xiangdong from the School of Physics at Beijing Institute of Technology (BIT) has achieved a groundbreaking advancement in the realm of topological circuits, successfully designing and fabricating a novel "topological space-time circuit." The findings, titled "Topolectrical space-time circuits," have been published in the prestigious journal Nature Communications. Researchers Zhang Weixuan, doctoral students Cao Wenhui, and Qian Long share the honor of being the co-first authors, with Professor Zhang Xiangdong serving as the corresponding author. This research endeavor was generously supported by the National Key R&D Program of China and the National Natural Science Foundation of China.
