研究目的
Investigating the use of two photon interference in a three-level system to sense coherent phonons, accounting for coherent phonon coupling using a full quantum–mechanical treatment.
研究成果
The study proposes a novel scheme for sensing coherent phonons using two photon interference in a three-level system, demonstrating potential applications in understanding coherent bosonic multi-pathway interference effects. The theoretical findings suggest observable effects like asymmetry in the excited state population and anomalous EIT dispersion, which could serve as indicators for coherent phonons.
研究不足
The study is theoretical and lacks experimental validation. The practical implementation of the proposed method may face challenges such as phase fluctuation in optical or phonon fields and the need for generating phonons in a coherent manner with the same laser field.
