By chiral coupling we mean an asymmetric coupling of the atomic decay to the left and right propagating guided modes. We formulate a quantum optical master equation treatment for this non-equilibrium dynamics Remarkably, our master equation predicts steady states in form of pure states consisting of quantum dimers (a dissipative 1D valence bond solid), or entangled spin-clusters. Our model has a natural realization with atoms coupled to nanofibers or nanostructures, or with spin chains coupled by dipolar interactions (trapped ions or polar molecules). We conclude with a theory outlook on how modern many-body quantum techniques (DMRG) can be applied to efficiently compute non-Markovian dynamics in a quantum optics context.
