“…However, nonreciprocal interactions are found almost everywhere, from aggregates of neurons to self-motile active particles, see, e.g., [13]. Populations of phase oscillators with asymmetric couplings are found in models inspired in neuroscience [14,15], society [16], hydrodynamically coupled flagella [17], etc. The effect of nonreciprocity on glassy phases in the context of synchronization is attracting attention [18] but remains scarcely explored; particularly in comparison to random neural networks, see, e.g., the discussion in [19,20] and references therein.…”
