微波场控制下的电磁诱导透明.

Based on the Λ-type level system in quantum mechanics, a three-level Λ-type system model with double electric field driven by microwave is established. The differential equation of the detection field is derived by the system density matrix, and is simulated by four order Runge Kutta numerical method. The steady state absorption properties of the system are studied, the interaction field and the atomic energy level system are analyzed. The results show that when the detuning is zero, the detection field could present a slight oscillation, almost no absorption propagation; when the detuning is not zero, the intensity of the detection field decreases sharply with the inerease of detuning, and electromagnetically induced parency occurs. Therefore, the coherence theory is used to explore its physical mechanism. The strength of detection field will greatly decay as the detuning amount is nonzero. The calculation results implements the electromagnetic induction of transparent with the microwave fields and provide a clear information for related research. [ABSTRACT FROM AUTHOR]
