- 요약More than three decades after the first report of the high-transition-temperature superconductivityin doped copper-oxides (cuprates) in 1986[1], the microscopic mechanism of its superconductivityremains an open question and a standing research focus in the field of condensedmatter physics. The normal state of the cuprate superconductors as signified by the well-known"strange-metal" behavior with a linear-in-temperature scattering rate, is not any less intriguingand has evoked comparably intensive research endeavor. On the other hand, researchers had neverlost momentum in their dedicated pursuit of superconductivity in analogue compounds that arebased on other transition metals, with the effort being paid off by successively discovered superconductivityin iron pnictides[2], ruthenates[3], and more recently in nickelates[4], which has sparkedcomprehensive examination on their superconducting and normal-state properties, as well as theirsimilarities and discrepancies compared to the prototypical cuprate superconductors. In this thesis,we leverage the power of a unified power-law-liquid(PLL) form of scattering rate, first by applyingit on the transport data of Bi2Sr2CaCu2O8+δ("Bi-2212") materials with a broad doping range,connecting the parameters directly to a previously reported PLL-ARPES study on Bi-2212, andthen by extending the ARPES study to three other classes of superconductivity-related materials:Sr2RuO4, Pr4Ni3O8, and near optimally-doped La2-x SrxCuO2 (LSCO), eventually drawinga quantitative comparison between their many-body correlation strengths and the quasiparticlescattering rates.
