Observation of hidden altermagnetism in CsVTeO
Guowei Yang, Ruihan Chen, Changchao Liu +25
Altermagnets are characterized by anisotropic band/spin splittings in momentum space, dictated by their spin-space group symmetries. However, the real-space modulations of altermag…
Dimensionality tuning of heavy-fermion states in ultrathin CeSi2 films
Yi Wu, Weifan Zhu, Teng Hua +18
Dimensionality tuning is an important method to modify the electronic states of quantum materials. However, the mechanism of such tuning in heavy fermion systems and its connection…
Multigap nodeless superconductivity in Dirac semimetal PdTe
Fengrui Shi, Weilong Qiu, Chufan Chen +12
PdTe has recently been reported to be a type-II Dirac semimetal while a bulk nodal and surface nodeless superconductivity (SC) has been claimed to coexist. In this work, we applied…
Large ferromagnetic-like band splitting in ultrathin films
Hao Zheng, Yifu Xu, Guowei Yang +9
Two-dimensional (2D) magnetic materials provide a unique platform for exploring quantum phases from magnetic order in reduced dimensions. While there have been extensive studies on…
flat bands and coupled moments in the kagome-honeycomb permanent magnet SmCo
Hao Zheng, Zhiguang Xiao, Ze Pan +19
Rare earth permanent magnets (REPMs) with both localized moments and itinerant conduction bands are not only important for fundamental research but also have significant technologi…
Orientation-dependent superconductivity and electronic structure of the rare-earth metal/KTaO3 interfaces
Guowei Yang, Weifan Zhu, Jiawen Zhang +10
The recent discovery of orientation-dependent superconductivity in KTaO3-based interfaces has attracted considerable interest, while the underlying origin remains an open question.…
