Area of Science:

• Quantum Chemistry
• Molecular Physics
• Spectroscopy

Background:

• Chiral molecules exist as non-superimposable mirror images (enantiomers).
• Controlling enantiomer-specific states is crucial for chemical synthesis and pharmaceutical development.
• Enantio-specific state transfer (ESST) is a key technique for distinguishing and manipulating chiral molecules.

Purpose of the Study:

• To propose a simple and efficient dynamical method for fast enantio-specific state transfer (ESST) in chiral molecules.
• To provide a theoretical framework for achieving ESST using external electromagnetic fields.
• To explore the robustness and experimental feasibility of the proposed method.

Main Methods:

• Modeling chiral molecules as cyclic three-level systems.
• Applying three external electromagnetic fields to drive the system.
• Analyzing the conditions for ESST based on Rabi frequencies and field amplitudes.
• Investigating the impact of arbitrary field waveforms on ESST.

Main Results:

• A simple dynamical method for fast ESST of chiral molecules is proposed.
• ESST is achievable when the amplitudes of three Rabi frequencies in the cyclic three-level system are equal.
• The method demonstrates robustness and high efficiency.
• Arbitrary waveforms of external fields can be employed, simplifying experimental implementation.

Conclusions:

• The proposed dynamical method offers a straightforward and efficient route to fast ESST.
• Equal Rabi frequencies are identified as the key condition for successful ESST.
• The flexibility in field waveform design enhances the practical applicability of the method in experimental settings.
