We study the thermodynamic properties induced by non-reciprocal interactions between
stochastic degrees of freedom in time- and space-continuous systems. We show that, under fairly
general conditions, non-reciprocal coupling alone implies a steady energy flow through the system,
i.e., non-equilibrium. Projecting out the non-reciprocally coupled degrees of freedom renders
non-Markovian, one-variable Langevin descriptions with complex types of memory, for which we
find a generalized second law involving information flow.We demonstrate that non-reciprocal
linear interactions can be used to engineer non-monotonic memory, which is typical for, e.g.,
time-delayed feedback control, and is automatically accompanied with a nonzero information flow
through the system. Furthermore, already a single non-reciprocally coupled degree of freedom can
extract energy from a single heat bath (at isothermal conditions), and can thus be viewed as a
minimal version of a time-continuous, autonomous ‘Maxwell demon’.We also show that for
appropriate parameter settings, the non-reciprocal system has characteristic features of active
matter, such as a positive energy input on the level of the fluctuating trajectories without global
particle transport.
