Engineering excitonic metal-insulator transitions in ultra-thin doped copper sulfides
Haiyang Chen, Yufeng Liu, Yashi Jiang +10
Delicate engineering of the bands remains challenging due to complex electronic, structural, and compositional interplay. We demonstrate the formation of distinct metallic and insu…
Surface reconstruction and orthogonal decoupling in SrAl4 and EuAl4
Tongrui Li, Leiyuan Chen, Jian Yuan +10
Surface-induced symmetry breaking in quantum materials can stabilize exotic electronic phases distinct from those in the bulk, yet its momentum-space manifestations remain elusive…
Observation of multiple surface states in naturally cleavable chiral crystal PdSbSe
Zhicheng Jiang, Zhengtai Liu, Chenqiang Hua +11
Chiral multifold fermions in solids exhibit unique band structures and topological properties, making them ideal for exploring fundamental physical phenomena related to nontrivial…
Large band-splitting in -wave type altermagnet CrSb
Jianyang Ding, Zhicheng Jiang, Xiuhua Chen +19
Altermagnetism (AM), a newly discovered magnetic state, ingeniously integrates the properties of ferromagnetism and antiferromagnetism, representing a significant breakthrough in t…
Absence of altermagnetic spin splitting character in rutile oxide RuO
Jiayu Liu, Jie Zhan, Tongrui Li +19
Rutile RuO has been posited as a potential -wave altermagnetism candidate, with a predicted significant spin splitting up to 1.4 eV. Despite accumulating theoretical predict…
