  Strange or bad metallic transport, defined by its incompatibility with
conventional quasiparticle pictures, is a theme common to strongly correlated
materials and ubiquitous in many high temperature superconductors. The Hubbard
model represents a minimal starting point for modeling strongly correlated
systems. Here we demonstrate strange metallic transport in the doped
two-dimensional Hubbard model using determinantal quantum Monte Carlo
calculations. Over a wide range of doping, we observe resistivities exceeding
the Mott-Ioffe-Regel limit with linear temperature dependence. The temperatures
of our calculations extend to as low as 1/40 the non-interacting bandwidth,
placing our findings in the degenerate regime relevant to experimental
observations of strange metallicity. Our results provide a foundation for
connecting theories of strange metals to models of strongly correlated
materials.
