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…

Quantics Tensor Cross Interpolation for High-Resolution, Parsimonious Representations of Multivariate Functions in Physics and Beyond

Marc K. Ritter, Yuriel Núñez Fernández, Markus Wallerberger +3

Multivariate functions of continuous variables arise in countless branches of science. Numerical computations with such functions typically involve a compromise between two contrar…
