DOI: 10.1038/s41467-020-16425-z
Abstract: The evolution of Sr2IrO4 upon carrier doping has been a subject of intense interest, due to its similarities to the parent cuprates, yet the intrinsic behaviour of Sr2IrO4 upon hole doping remains enigmatic. Here, we… read more here.

DOI: 10.1038/s41467-021-23347-x
Abstract: It is widely thought that the water-oxidation reaction limits the maximum work function to about 5.25 eV for hole-doped semiconductors exposed to the ambient, constrained by the oxidation potential of air-saturated water. Here, we show that… read more here.

DOI: 10.1038/s41535-019-0198-4
Abstract: Spin-resonance modes (SRM) are taken as evidence for magnetically driven pairing in Fe-based superconductors, but their character remains poorly understood. The broadness, the splitting and the spin-space anisotropies of SRMs contrast with the mostly accepted… read more here.

DOI: 10.1038/s41598-021-91163-w
Abstract: Electron–boson spectral density functions (EBSDFs) can be obtained from measured spectra using various spectroscopic techniques, including optical spectroscopy. EBSDFs, known as glue functions, are suggested to have a magnetic origin. Here, we investigated EBSDFs obtained… read more here.

DOI: 10.1103/physrevb.101.245112
Abstract: We investigate electronic properties of hole-doped cuprates ${\mathrm{Mg}}_{1\ensuremath{-}x}{\mathrm{Li}}_{x}{\mathrm{Cu}}_{2}{\mathrm{O}}_{3}$ with the quasi-one-dimensional two-leg-ladder structure. We succeeded in extending the solubility limit of Li in ${\mathrm{Mg}}_{1\ensuremath{-}x}{\mathrm{Li}}_{x}{\mathrm{Cu}}_{2}{\mathrm{O}}_{3}$ from $x=0.12$ to $x=0.60$ by using the high-pressure synthesis technique.
