| contents | Chirality, the absence of mirror symmetry, is a fundamental molecular property with far-reaching consequences from chemistry to biology. Yet enantiosensitive optical responses are very weak. Here, we introduce a theoretical framework in which a chiral optical cavity under strong coupling directly lifts the degeneracy of opposite enantiomers at the electronic-dipole level. The cavity's parity-breaking field inside the cavity induces distinct site-energy shifts for left- versus right-handed molecules, producing robust enantioselective polariton states that overcome the weakness of traditional chiroptical effects. Using cavity quantum electrodynamics simulations, we show that strong light-matter coupling reshapes the polaritonic energy landscape and leads to enantiomer-specific coherence lifetimes and relaxation pathways. To reveal these dynamics, we propose ultrafast two-dimensional electronic spectroscopy (2DES) as a probe, capable of resolving polaritonic splittings on femtosecond timescales. Simulated 2DES spectra exhibit unambiguous enantioselective signatures of the cavity-induced asymmetry. These findings establish that chiral cavities provide a powerful platform for detecting and controlling molecular handedness beyond the limits of conventional optical methods. |
