Abstract We have theoretically and experimentally studied the quantum coherence effects of a degenerate transition $F_g = 3 \leftrightarrow F_e = 2$ system interacting with a weak linearly polarized (with $\sigma _\pm $ components) probe light and a strong linearly polarized (with $\sigma _\pm $ 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. ${\Delta} e > {\Delta} g)$.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
