Description
Non-reciprocal interactions violate the action-reaction symmetry of Newton’s third law, giving rise to phenomena such as amplification, synchronization, and spontaneous parity-time symmetry breaking. In quantum systems, non-reciprocal interactions have recently attracted significant interest as a new tool to engineer functionality, with potential for sensing and signal processing applications. Here we report experiments on non-reciprocal interactions in a hybrid mechanical-atomic system coupled by light. We observe spontaneous coupled oscillations, two-mode squeezing dynamics, limit cycles and phase synchronization of the two systems.
