Evidence for an Excitonic Insulator State in TaPdTe
Jierui Huang, Bei Jiang, Jingyu Yao +30
The excitonic insulator (EI) is an exotic ground state of narrow-gap semiconductors and semimetals arising from spontaneous condensation of electron-hole pairs bound by attractive…
Direct observation of topological surface states in the layered kagome lattice with broken time-reversal symmetry
Zhicheng Jiang, Tongrui Li, Jian Yuan +14
Magnetic topological quantum materials display a diverse range of fascinating physical properties which arise from their intrinsic magnetism and the breaking of time-reversal symme…
Photoemission Evidence of a Novel Charge Order in Kagome Metal FeGe
Zhisheng Zhao, Tongrui Li, Peng Li +16
A charge order has been discovered to emerge deep into the antiferromagnetic phase of the kagome metal FeGe. To study its origin, the evolution of the low-lying electronic structur…
Kagome surface states and weak electronic correlation in vanadium-kagome metals
Jianyang Ding, Ningning Zhao, Zicheng Tao +10
RV6Sn6 (R = Y and lanthanides) with two-dimensional vanadium-kagome surface states is an ideal platform to investigate kagome physics and manipulate the kagome features to realize…
Spectroscopic signature of obstructed surface states in SrInP
Xiang-Rui Liu, Hanbin Deng, Yuntian Liu +13
The century-long development of surface sciences has witnessed the discoveries of a variety of quantum states. In the recently proposed "obstructed atomic insulators", insulators w…
Observation of plaid-like spin splitting in a noncoplanar antiferromagnet
Yu-Peng Zhu, Xiaobing Chen, Xiang-Rui Liu +27
Spatial, momentum and energy separation of electronic spins in condensed matter systems guides the development of novel devices where spin-polarized current is generated and manipu…
Chiral Dirac fermion in a collinear antiferromagnet
Ao Zhang, Ke Deng, Jieming Sheng +18
In a Dirac semimetal, the massless Dirac fermion has zero chirality, leading to surface states connected adiabatically to a topologically trivial surface state as well as vanishing…
