We show that atomic Fermi mixtures with density and mass imbalance exhibit arich diversity of scaling laws for the quasiparticle decay rate beyond thequadratic energy and temperature dependence of conventional Fermi liquids. Forcertain densities and mass ratios, the decay rate is linear whereas in othercases it exhibits a plateau. Remarkably, this plateau extends from the deeplydegenerate to the high temperature classical regime of the light species. Manyof these scaling laws are analogous to what is found in very different systemsincluding dirty metals, liquid metals, and high temperature plasmas. The Fermimixtures can in this sense span a whole range of seemingly diverse and separatephysical systems. Our results are derived in the weakly interacting limitmaking them quantitatively reliable. The different regimes can be detected withradio-frequency spectroscopy.
