Author(s): Marie Sellier-Prono, Massimo Cencini, David Kleinfeld, and Massimo Vergassola
Spatial nonhomogeneities can synchronize clusters of spatially extended oscillators in different frequency plateaus. Motivated by physiological rhythms, we fully characterize the phase diagram of a Ginzburg-Landau (GL) model with a gradient of frequencies. For large gradients and diffusion, the rest… [Phys. Rev.
