However, Planckian considerations in general apply only to the "inelastic" scattering rate, whereas electron-phonon scattering is quasi-elastic at T > ω_0. Hence, even if the Planckian bound were true, it would not explain the observed bound on λ in conventional metals at high temperatures. I will discuss recent Monte Carlo results on the paradigmatic Holstein model which show that a very different sort of bound is at play here: a "stability" bound on λ consistent with metallic transport [4]. I will then speculate that a qualitatively similar bound on the strength of residual interactions, which is often stronger than Planckian, may apply to metals more generally.
