Information, Dissipation, and Planckian Optimality
Debanjan Chowdhury
We derive a universal bound on the efficiency with which "dissipated" work can generate distinguishable changes in a quantum many-body state at a finite temperature, as quantified…

Planckian Bounds via Spectral Moments of Optical Conductivity
Debanjan Chowdhury
The observation of Planckian scattering, often inferred from Drude fits in strongly correlated metals, raises the question of how to extract an intrinsic timescale from measurable…
