Bad metals display transport behavior that differs from what is commonly seenin ordinary metals. One of the most significant differences is a resistivitythat is linear in temperature and rises to well above the Ioffe-Regel limit(where the mean-free path is equal to the lattice spacing). Using an exact Kuboformula, we show that a linear resistivity naturally occurs for many systemswhen they are in an incoherent intermediate-temperature state. We verify theanalytic arguments with numerical calculations for a simplified version of theHubbard model which is solved with dynamical mean-field theory. Similarfeatures have also been seen in Hubbard models, where they can begin at evenlower temperatures due to the formation of resilient quasiparticles.
