Anti-higher-order Weyl semimetal
Cheng-Ming Miao, Yu-Hao Wan, Qing-Feng Sun
Higher-order topology extends the bulk-boundary correspondence by enabling corner or hinge localized states. Here we identify an anti-higher-order Weyl semimetal, a three dimension…
Anti-higher-order topological insulators
Cheng-Ming Miao, Yu-Hao Wan, Ying-Tao Zhang +1
Duality is a fundamental concept in physics that connects complementary opposites like particles and holes. Similarly, while topological states in topological insulators localize a…
Spin-textured orbitals in altermagnetic artificial atoms
Yue Mao, Yu-Chen Zhuang, Cheng-Ming Miao +2
Artificial atoms provide a versatile platform for engineering atomic-like orbitals, yet spin generally remains a passive degree of freedom in their orbital structure. Here, we intr…
