    "abstract": "This is a study of front dynamics in reaction diffusion systems near\nNonequilibrium Ising-Bloch bifurcations. We find that the relation between\nfront velocity and perturbative factors, such as external fields and curvature,\nis typically multivalued. This unusual form allows small perturbations to\ninduce dynamic transitions between counter-propagating fronts and nucleate\nspiral vortices. We use these findings to propose explanations for a few\nnumerical and experimental observations including spiral breakup driven by\nadvective fields, and spot splitting.",
