  "abstract": "Non-reciprocal interactions, in general, break detailed balance. We study an active particle system where activity originates from asymmetric, pairwise interaction forces that result in an injection of energy at the microscopic scale. Using a field theory that captures microscopic dynamics, we calculate correlation functions and the entropy production to characterise the non-equilibrium properties of this many-particle active system in the stationary state. We support our analytical results with numerical simulations.",
