Quantum interference effects in a multi-driven transition F-g=3 <-> F-e=2

We have theoretically and experimentally studied the quantum coherence effects of a degenerate transition F. 3 <-> F-c = 2 system interacting with a weak linearly polarized (witho sigma+/- components) probe light and a strong linearly polarized (with sigma+/- components) coupling field. Due to the competition between the drive Rabi frequency and the Zeeman splitting, electromagnetically induced transparency (EIT) and electromagnetically induced absorption (EIA) are present at the different values of applied magnetic field in the case where the Zeeman splitting of excited state Delta e is larger than the Zeeman splitting of ground state Delta g (i.e. Delta e > Delta g).
