Orbital Altermagnetic Photonic Crystal
Sichang Qiu, Huichang Li, Yan Meng +6
Altermagnetism features momentum-dependent spin splitting without net magnetization, extending spintronics beyond conventional ferromagnetism and antiferromagnetism. However, the p…
Anomalous Topological Bloch Oscillations under Non-Abelian Gauge Fields
Chunyan Li, Ce Shang, Boris A. Malomed
Topological Bloch oscillations are a hallmark of quantum transport phenomenon in which wavepackets undergo oscillatory motion driven by the interplay between an external force and…
Deep-Learning-Empowered Programmable Topolectrical Circuits
Hao Jia, Shanglin Yang, Jiajun He +9
Topolectrical circuits provide a versatile platform for exploring and simulating modern physical models. However, existing approaches suffer from incomplete programmability and ine…
Free Extension of Topological States via Double-zero-index Media
Rui Dong, Changhui Shen, Changqing Xu +2
Topological states, known for their robustness against disorder, offer promising avenues for disorder-resistant devices. However, their intrinsic spatial confinement at interfaces…
