Description
I will present our recent findings on pattern formation in non-reciprocal mixtures. First, I will discuss a disorder-to-order transition and new kind of defect interactions in the Nonreciprocal Cahn-Hilliard model. I will then highlight the role of hydrodynamics and demonstrate how nonreciprocity couples with nonlinearities to stabilize fluctuating polar order against linear Stokesian instabilities.
