Spontaneous Fully Compensated Ferrimagnetism
Bingbing Wang, Yongpan Li, Yichen Liu +1
We propose a general mechanism for the spontaneous emergence of filling-enforced fully compensated ferrimagnetism (fFIM), characterized by zero net magnetization yet ferromagnetic-…
Unconventional Magneto-Optical Effects in Altermagnets
Yongpan Li, Yichen Liu, Cheng-Cheng Liu
The ideal altermagnets are a class of collinear, crystal-symmetry-enforced fully compensated magnets with nonrelativistic spin-split bands, in which contributions from Berry curvat…
Quantum metric-based optical selection rules
Yongpan Li, Cheng-Cheng Liu
The optical selection rules dictate symmetry-allowed/forbidden transitions, playing a decisive role in engineering exciton quantum states and designing optoelectronic devices. Whil…
Quantum metric-induced generalized magneto-optical effects in -symmetric antiferromagnets
Yongpan Li, Yichen Liu, Cheng-Cheng Liu
The magneto-optical effects (MOEs), as fundamental physical phenomena, can reveal the electronic structures of materials. The related probing methods are widely used in the study o…
Two-dimensional fully-compensated Ferrimagnetism
Yichen Liu, San-Dong Guo, Yongpan Li +1
Antiferromagnetic spintronics has long been a subject of intense research interest, and the recent introduction of altermagnetism has further ignited enthusiasm in the field. Howev…
Stable Higher-Order Topological Dirac Semimetals with Monopole Charge in Alternating-twisted Multilayer Graphenes and beyond
Shifeng Qian, Yongpan Li, Cheng-Cheng Liu
We demonstrate that a class of stable monopole charge Dirac point (DP) phases can robustly exist in real materials, which surmounts the understanding:…
Layer Construction of Three-Dimensional Z2 Monopole Charge Nodal Line Semimetals and prediction of the abundant candidate materials
Yongpan Li, Shifeng Qian, Cheng-Cheng Liu
The interplay between symmetry and topology led to the concept of symmetry-protected topological states, including all non-interacting and weakly interacting topological quantum st…
