Adding non-linearity to a non-reciprocal system enables the two molecule species to change their dynamics. As a result, both run-and-chase interactions and phase separation can exist at the same time in the system. Credit: MPI-DS, LMP<\/p>\n

Asymmetric interactions between different species of molecules have previously been demonstrated to result in self-organized patterns and functions. If one species A is attracted to B, but in turn, B is repelled by A, run-and-chase dynamic emerges.<\/p>\n

This is a common phenomenon observed in minimal models of living matter. In contrast<\/a>, if the attraction<\/a> and repulsion<\/a> are mutual, the system typically acquires a more static state with separated phases\u2014such as oil droplets in water.<\/p>\n

Suropriya Saha and Ramin Golestanian from the department of Living Matter Physics at MPI-DS have now extended the model of non-reciprocal interactions. They investigated what would happen to the system if the role of the two molecule species were not linear. Their findings are published<\/a> in Nature Communications.<\/p>\n

“When we introduce nonlinearity into the system, the resulting behavior becomes dynamic and unpredictable,” explains Saha, the first author of the study. “This means that the roles of molecule A and B can be reversed, spontaneously reversing the roles in the run-and-chase interaction\u2014or also acquiring a reciprocal behavior. Nonlinearities arise generically in real systems in nature, yielding to a more comprehensive model describing living matter.”<\/p>\n

The result of such nonlinear non-reciprocal interactions is the coexistence of run-and-chase dynamics and phase separation. Moreover, since the role of the two species<\/a> can reverse dynamically, the entire system becomes chaotic.<\/p>\n

“In living systems, such non-reciprocal interactions are more the rule than the exception,” says Golestanian. “Hence this model<\/a> reflects the versatile dynamics of living systems and thus helps us understand the complexity of how matter can organize and contribute to the formation of life.”<\/p>\n
