Uniaxial-Strain Tuning of the Intertwined Orders in BaFe(AsP)
Zinan Zhao, Ding Hu, Xue Fu +5
An experimental determination of electronic phase diagrams of high-transition temperature (high-) superconductors forms the basis for a microscopic understanding of unconventi…
Exchange field enhanced upper critical field of the superconductivity in compressed antiferromagnetic EuTe2
Hualei Sun, Liang Qiu, Yifeng Han +17
We report high pressure studies on the C-type antiferromagnetic semiconductor EuTe2 up to 36.0 GPa. A structural transition from the I4/mcm to C2/m space group is identified at ~16…
Single crystal growth and superconductivity in RbNiSe
Hui Liu, Xunwu Hu, Hanjie Guo +14
We report the synthesis and characterization of RbNiSe, an analog of the iron chalcogenide superconductor RbFeSe, via transport, angle resolved photoemission sp…
Nematic fluctuations in the non-superconducting iron pnictide BaFeNiCrAs
Dongliang Gong, Ming Yi, Meng Wang +16
The main driven force of the electronic nematic phase in iron-based superconductors is still under debate. Here, we report a comprehensive study on the nematic fluctuations in a no…
Complex structure due to As bonding and interplay with electronic structure in superconducting BaNi2As2
Bing-Hua Lei, Yucheng Guo, Yaofeng Xie +3
BaNi2As2 is a superconductor chemically related to the Fe-based superconductors, with a complex and poorly understood structural phase transition. We show based on first principles…
Tunable nodal kagome superconductivity in charge ordered RbV3Sb5
Z. Guguchia, C. Mielke, D. Das +18
Unconventional superconductors often feature competing orders, small superfluid density, and nodal electronic pairing. While unusual superconductivity has been proposed in the kago…
