Abstract
We propose an enantio-detection method of chiral molecules in a cavity with external drive. The chiral molecules are coupled with a quantized cavity field and two classical light fields to form the cyclic three-level systems. The chirality-dependent cavity-assisted three-photon process in the three-level systems leads to the generation of intracavity photons. Simultaneously, the drive field also results in the chirality-independent process of the generation of intracavity photons. Based on the interference between the intracavity photons generated from these two processes, one can detect the enantiomeric excess of chiral mixture via monitoring the transmission rate of the drive field.

Summary
The existence of two molecular structural forms known as enantiomers (left- and right-handed chiral molecules) is one of the most important manifestations of symmetry breaking in nature [1]. We propose an enantiodetection method based on the CQED system for cyclic three-level chiral molecules, which are located in a traveling-wave cavity [66,67,68] with an external drive. There is no external drive to the cavity in the previous system [54] and additional enantiopure samples are required to further determine the sign of the enantiomeric excess of the chiral mixture in the enantiodetection therein.
