Electromagnetically induced transparency in a V-system with 87Rb vapor in the hyperfine Paschen--Back regime [dataset]

We observe EIT in a V-system in a thermal rubidium 87 vapor in the hyperfine Paschen--Back regime, realized with a 0.6 T axial magnetic field. In this regime energy levels are no longer degenerate and EIT features from different initial states are distinct. We compare our results to a model using the time-dependent Lindblad master equation, and having averaged over a distribution of interaction times, see good qualitative agreement for a range of pump Rabi frequencies. Excited state decay into both ground states is shown to play a prominent role in the generation of the transparency feature, which arises mainly due to transfer of population into the ground state not coupled by the probe beam.
