The authors propose here a mechanism and an explicit one-dimensional model to realize the linear-in-temperature resistivity that is the hallmark of bad metals. They then verify the behavior with advanced DMRG-type simulations. These results open a new approach to understanding the limits of relaxation generated by local interactions in extended many-body systems. This work should push forward research into understanding some of the most basic questions about transport for 1D and critical systems, which bridge quantum matter and quantum chaos.
