Bad metal data versus a theory of non-linear diffusion — Matthias Kaminski¹, •Navid Abbasi², and Omid Tavakol³ — ¹University of Alabama, Tuscaloosa, USA — ²Lanzhou University, Lanzhou, China — ³University of Toronto, Toronto, Canada

In a system with one conserved charge the charge diffusion is modified by non-linear self-interactions within an effective field theory (EFT) of diffusive fluctuations. We include the slowest ultraviolet (UV) mode, constructing a UV-regulated EFT of non-linear diffusion. Predictions from this theory are in agreement with experimental data in a bad metal system.
