Non-Hermitian chirality in optomechanical networks

Our work on new mechanisms to control the flow of sound with light was published in Nature today. Congratulations to Javier and Jesse! By using radiation pressure control, we break time-reversal symmetry and introduce mechanical squeezing at the same time. We find that this allows broad control over the non-Hermitian dynamics of small nanomechanical networks, with symmetry breaking, nonreciprocity, and chiral amplification as a result.
