Nonlinear Diffusion and Decay of an Expanding Turbulent Blob
Takumi Matsuzawa, Minhui Zhu, Nigel Goldenfeld +1
Turbulence, left unforced, decays and invades the surrounding quiescent fluid. Though ubiquitous, this simple phenomenon has proven hard to capture within a simple and general fram…

Self-consistent expansion and field-theoretic renormalization group for a singular nonlinear diffusion equation with anomalous scaling
Minhui Zhu, Nigel Goldenfeld
The method of self-consistent expansions is a powerful tool for handling strong coupling problems that might otherwise be beyond the reach of perturbation theory, providing surpris…
