Web2 dagen geleden · We investigate a scheme for observing the third-order exceptional point (EP3) in an ion-cavity system. In the lambda-type level configuration, the ion is driven by a pump field, and the resonatoris probed with another weak laser field. We exploit the highly asymmetric branching ratio of an ion's excited state to satisfy the weak-excitation limit, … WebDetermine the spectator ions.
