Nonsymmorphic symmetry protected node-line semimetal in the trigonal YH3
Dexi Shao, Tong Chen, Qinyan Gu +5
Using ab initio calculations based on density-functional theory and effective model analysis, we propose that the trigonal YH3(Space Group: P-3c1) at ambient pressure is a node-lin…
High-pressure phases of Weyl semimetals NbP, NbAs, TaP and TaAs
Zhaopeng Guo, Pengchao Lu, Tong Chen +3
The high pressure phase diagrams of TaAs family (NbP, NbAs, TaP and TaAs) are explored systematically using crystal structure search together with first-principles calculations. Ou…
High temperature superconducting phase of HBr under pressure predicted by first-principles calculations
Qinyan Gu, Pengchao Lu, Kang Xia +2
The high pressure phases of HBr are explored with an ab initio crystal structure search. By taking into account the contribution of zero-point energy (ZPE), we find that the P4/nmm…
Direct Visualization of 2D Topological Insulator in Single-layer 1T'-WTe2
Zhen-Yu Jia, Ye-Heng Song, Xiang-Bing Li +9
We grow nearly freestanding single-layer 1T'-WTe2 on graphitized 6H-SiC(0001) by using molecular beam epitaxy (MBE), and characterize its electronic structure with scanning tunneli…
Pressure-induced metallization and superconducting phase in ReS2
Dawei Zhou, Yonghui Zhou, Chunying Pu +10
Among the family of TMDs, ReS2 takes a special position, which crystalizes in a unique distorted low-symmetry structure at ambient conditions. The interlayer interaction in ReS2 is…
Superconductivity Induced by High Pressure in Weyl Semimetal TaP
Yufeng Li, Yonghui Zhou, Zhaopeng Guo +13
Weyl semimetal defines a material with three dimensional Dirac cones which appear in pair due to the breaking of spatial inversion or time reversal symmetry. Superconductivity is t…

Kai-Wen Zhang, Chao-Long Yang, Bin Lei +8
By using scanning tunneling microscopy (STM) / spectroscopy (STS), we systematically characterize the electronic structure of lightly doped 1T-TiSe2, and demonstrate the existence…
Topological Dirac line nodes and superconductivity coexist in SnSe at high pressure
Xuliang Chen, Pengchao Lu, Xuefei Wang +15
Due to fundamental interest and potential applications in quantum computation, tremendous efforts have been invested to study topological superconductivity. However, bulk topologic…

Pengchao Lu, Joon-Seok Kim, Jing Yang +9
Tungsten ditelluride (WTe2) has attracted significant attention due to its interesting electronic properties, such as the unsaturated magnetoresistance and superconductivity. Recen…
The large unsaturated magnetoresistance of Weyl semimetals
Yiming Pan, Huaiqiang Wang, Pengchao Lu +3
The Weyl semimetal (WSM) is a novel topological gapless state with promises exotic transport due to chiral anomaly. Recently, a family of nonmagnetic WSM candidates including TaAs,…
A new topological semimetal with iso-energetic Weyl fermions in TaAs under high pressure
Yonghui Zhou, Pengchao Lu, Yongping Du +11
TaAs as one of the experimentally discovered topological Weyl semimetal has attracted intense interests recently. The ambient TaAs has two types of Weyl nodes which are not on the…
