While a specific kind of strange metal is increasingly found to be the"normal" states in a wide variety of unconventional superconductors, itsmicroscopic origin is presently a hotly debated enigma. Using dynamicalmean-field theory (DMFT) based on hybridization expansion of continuous-timequantum Monte-Carlo (CTQMC) solver for an extended two-band Hubbard model(2BHM), we investigate the conditions underlying the emergence of such a metal.Specifically, we tie strange metallicity to an orbital-selective Mottness in2BHM or momentum-selective Mott phase (OSMP) in 2D Hubbard models inspired by acluster-to-orbital mapping. We find $(i)$ disparate spin and charge responses,$(ii)$ fractional power-law behavior and $\omega/T$-scaling in the charge andspin fluctuation responses, and $(iii)$ very good accord with opticalconductivity and nuclear magnetic relaxation rates in the slightly underdopednormal states of cuprates and Fe-arsenides. We analyze the local problem usingbosonization to show that such anomalous responses arise from a latticeorthogonality catastrophe specifically in the OSMP. Our work establishes theintimate link between strange metallicity and selective Mottness in quantummatter.
