Strong charge density wave fluctuation and sliding state in PdTeI with quasi-1D PdTe chains
Hechang Lei, Kai Liu, Jun-ichi Yamaura +4
In quasi-one-dimensional (quasi-1D) system, the charge density wave (CDW) transition temperature TCDW is usually lower than the mean-field-theory predicted TMF and a CDW fluctuatio…
Type-I superconductivity in KBi2 single crystals
Shanshan Sun, Kai Liu, Hechang Lei
We report the detailed transport, magnetic, thermodynamic properties and theoretical calculation of KBi2 single crystals in superconducting and normal states. KBi2 shows metallic b…
First-principles study of FeSe epitaxial films on SrTiO3
Kai Liu, Miao Gao, Zhong-Yi Lu +1
The discovery of high temperature superconductivity in FeSe films on SrTiO3 substrate has inspired great experimental and theoretical interests. First-principles density functional…
Nematic antiferromagnetic states in bulk FeSe
Kai Liu, Zhong-Yi Lu, Tao Xiang
We revisit bulk FeSe through the systematic first-principles electronic structure calculations. We find that there are a series of staggered -mer antiferromagnetic (AFM) states…
Common Electronic Origin of Superconductivity in (Li,Fe)OHFeSe Bulk Superconductor and Single-Layer FeSe/SrTiO3 Films
Lin Zhao, Aiji Liang, Dongna Yuan +17
The mechanism of high temperature superconductivity in the iron-based superconductors remains an outstanding issue in condensed matter physics. The electronic structure, in particu…
Sudden gap-closure across the topological phase transition in BiInSe
Rui Lou, Zhonghao Liu, Wencan Jin +10
The phase transition from a topological insulator to a trivial band insulator is studied by angle-resoled photoemission spectroscopy on BiInSe single crystals.…
