Planckian dissipation bounds emerge as the requirement for classical hydrodynamics to stay valid at low temperature in quantum systems, via blurring from the quantum fluctuation-dissipation theorem.
A linearized Boltzmann model in five-terminal geometry shows current partition diagnoses ballistic-hydrodynamic-Ohmic crossover and extracts momentum-relaxing and conserving scattering rates.
Lectures summarizing the construction of hydrodynamic EFTs through strong-to-weak symmetry breaking, with examples from spin chains to relativistic QFTs and UV/IR constraints on transport coefficients.
