Realization of metallic state in 1T-TaS2 with persisting long-range order of charge density wave
Xin-Yang Zhu, Shi Wang, Zhen-Yu Jia +10
Metallization of 1T-TaS2 is generally initiated at the domain boundary of charge density wave (CDW), at the expense of its long-range order. However, we demonstrate in this study t…
Evidence for singular-phonon-induced nematic superconductivity in a topological superconductor candidate SrBiSe
Jinghui Wang, Kejing Ran, Shichao Li +11
Superconductivity mediated by phonons is typically conventional, exhibiting a momentum-independent s-wave pairing function, due to the isotropic interactions between electrons and…
Topological flat bands in twisted trilayer graphene
Zhen Ma, Shuai Li, Ya-Wen Zheng +4
Twisted trilayer graphene (TLG) may be the simplest realistic system so far, which has flat bands with nontrivial topology. Here, we give a detailed calculation about its band stru…
Quantum valley Hall effect, orbital magnetism, and anomalous Hall effect in twisted multilayer graphene systems
Jianpeng Liu, Zhen Ma, Jinhua Gao +1
We study the electronic structures and topological properties of -layer twisted graphene systems. We consider the generic situation that -layer graphene is placed on top…
Flat band localization due to self-trapped orbital
Zhen Ma, Wei-Jin Chen, Yuntian Chen +2
We discover a new wave localization mechanism in a periodic system without any disorder, which can produce a novel type of perfect flat band and is distinct from the known localiza…
