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…
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-…
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…
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…
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…
