We have developed quantum acoustics along the lines of quantum optics. Far from being of only pedagogical interest, it allows us to solve previously intractable electron-lattice vibration problems, by moving away from number state, particle (phonon) based theory to the coherent state, wave based picture. Much strange metal physics has come into focus, within a basic Fröhlich Hamiltonian treated nonperturbatively and coherently. A new many-body quantum acoustic mean field "wave-on-wave" code has seen Planckian resistivity, polarons, and CDW form spontaneously on a laptop in solid state systems using strange metal parameters. We have found the transport to be Planckian diffusive in the strange metal phase, with perfectly linear in T resistivity. We understand the transition to the pseudogap phase and will explain the quantum criticality and strong correlation so often cited in connection with the strange metals. We have generalized Anderson localization to the case of active random media and discovered that Planckian diffusion results over very large parameter ranges.
