Description

Nonreciprocal interactions between two agents, A and B, indicate that A exerts an influence on B different from the influence that B exerts on A. For instance, A may chase B which in turn runs away from A.
We present a quantum model of two spin species that interact in a nonreciprocal way. One species tends to synchronize in phase with the other species which in contrast tends to synchronize with a phase shift of $\pi$. We show that a dynamical state analogous to chase-and-run-away dynamics emerges. Our work extends the study of nonreciprocal interactions to the quantum domain.
