I will review the appearance of the Planckian time tau ~ hbar/(kB T) in both conventional and unconventional metals. I will then discuss the possibility of a Planckian bound on dissipation from both a quasiparticle and a many-body perspective. Planckian quasiparticles can arise naturally from a combination of inelastic scattering and mass renormalization. Many-body dynamics, on the other hand, is constrained by the basic timescales and length scales of local thermalization. This talk will be loosely based on the RMP published last year with Andy Mackenzie.

This talk is part of the Theory of Condensed Matter series.
