Classical-to-quantum transition of exceptional points induced by thermal noise
ORAL
Abstract
We study multiple effects of thermal noise on both the classical and quantum exceptional points in the experimental driven three-level system of Ref. [1]. In particular, we show that only in the absence of thermal noise the classical and quantum predictions are the same concerning exceptional points of non-Hermitian Hamiltonians and Liouvillians [2,3], respectively. Thus, thermal noise can induce a classical-to-quantum transition of exceptional points. This is a surprising result since thermal noise usually causes the opposite effect, i.e., a quantum-to-classical transition.
