DOI: 10.1002/andp.201800461
Abstract: Normal‐mode splitting (NMS) is one of the most significant manifestations of strongly coupled systems. Here, NMS is shown to occur in a weakly coupled electromechanical system. In this system, an exponentially enhanced electromechanical coupling is… read more here.
