Weyl points and spin-orbit coupling in copper-substituted lead phosphate apatite

Martin Braß, Liang Si, Karten Held

We study the impact of spin-orbit coupling on the topological band-properties of copper-substituted lead phosphate apatite using a combination of group-theoretical analysis and ful…

Electronic structure of the putative room-temperature superconductor Pb $_{9}$ Cu(PO $_{4}$ ) $_{6}$ O

Liang Si, Karsten Held

A recent paper [Lee {\em et al.}, J. Korean Cryt. Growth Cryst. Techn. {\bf 33}, 61 (2023)] provides some experimental indications that Pb $_{10 - x}$ Cu $_{x}$ (PO $_{4}$ ) $_{6}$ O with $x\appro…

Pb $_{10 - x}$ Cu $_{x}$ (PO $_{4}$ ) $_{6}$ O: a Mott or charge transfer insulator in need of further doping for (super)conductivity

Liang Si, Markus Wallerberger, Andriy Smolyanyuk +3

We briefly review the status quo of research on the putative superconductor Pb $_{9}$ Cu(PO $_{4}$ ) $_{6}$ O also known as LK-99. Further, we provide {\em ab initio} derived tight-binding par…

No superconductivity in Pb $_{9}$ Cu $_{1}$ (PO $_{4}$ ) $_{6}$ O found in orbital and spin fluctuation exchange calculations

Niklas Witt, Liang Si, Jan M. Tomczak +2

Finding a material that turns superconducting under ambient conditions has been the goal of over a century of research, and recently Pb $_{10 - x}$ Cu $_{x}$ (PO $_{4}$ ) $_{6}$ O aka LK-99 has be…

Ru doping induced spin frustration and enhancement of the room-temperature anomalous Hall effect in La2/3Sr1/3MnO3 films

Enda Hua, Liang Si, Kunjie Dai +9

In transition-metal-oxide heterostructures, the anomalous Hall effect (AHE) is a powerful tool for detecting the magnetic state and revealing intriguing interfacial magnetic orderi…

Effects of different concentrations of topotactic hydrogen impurities on the electronic structure of nickelate superconductors

Chenye Qin, Mi Jiang, Liang Si

Infinite-layer nickelate superconductors have recently been discovered to share both similarities and differences with cuprate superconductors. Notably, the incorporation of hydrog…
