This experimental research program is aimed at the study of atomic coherence and interference phenomena manifested by electromagnetically induced transparency (EIT) in cold atoms and the exploration of related applications in nonlinear optics and quantum optics. Because of the negligible Doppler broadening and the dense atomic density in a magneto-optical trap, cold atoms are well suited for the proposed studies, and quantitative comparison between experimental measurements and theoretical calculations can be obtained. Several research projects such as slow-light nonlinear wave mixing at low light intensities, which may lead to photon correlation and entanglement, EIT enhanced Kerr nonlinearity and cross phase modulation, group velocity matching for enhanced EIT nonlinearity, cavity meditated EIT, cavity enhanced EIT Kerr nonlinearity and cross phase modulations will be studied. The broader impact of the program involves student education, particularly of members of under-represented groups at the university.

该实验研究计划旨在研究冷原子中电磁感应透明（EIT）所表现的原子相干性和干涉现象，并探索非线性光学和量子光学中的相关应用。由于可以忽略的多普勒展宽和磁光阱中的原子密度，冷原子非常适合所提出的研究，并且可以获得实验测量和理论计算之间的定量比较。研究内容包括：低光强下的慢光非线性混频（可能导致光子关联和纠缠）、EIT增强的克尔非线性和交叉相位调制、增强EIT非线性的群速度匹配、腔介导EIT、腔增强EIT克尔非线性和交叉相位调制等。 该计划的更广泛影响涉及学生教育，特别是大学代表性不足群体的成员。
