Pressure-induced superconductivity in topological insulator Ge2Bi2Te5 and the evolution with Mn doping
Shangjie Tian, Qi Wang, Yuqing Cao +5
Introducing superconductivity (SC) or magnetism into topological insulators (TIs) can give rise to novel quantum states and exotic physical phenomena. Here, we report a high-pressu…
Three-dimensional topological insulator feature of ternary chalcogenide Ge2Bi2Te5
Shangjie Tian, Yuchong Zhang, Chenhao Liang +7
The exploration of novel topological insulators (TIs) beyond binary chalcogenides has been accelerated in pursuit of exotic quantum states and device applications. Here, the layere…
Cooperative concurrence of 4f and 3d flat bands in kagome heavy-fermion metal YbCr6Ge6
Wenxin Lv, Pengcheng Ma, Tianqi Wang +6
Flat-band (FB) systems originating from special lattice geometry like in kagome metals as well as localized orbitals in the materials such as heavy-fermion (HF) compounds have indu…
Nematic-fluctuation-mediated superconductivity in CuxTiSe2
Xingyu Lv, Yang Fu, Shangjie Tian +5
The interplay among electronic nematicity, charge density wave, and superconductivity in correlated electronic systems has induced extensive research interest. Here, we discover th…
