Electromagnetically Induced Transparency (EIT) and the Big Bang: The Sakharov Conditions on a table top

The Sakharov conditions met in the early universe may explain the matter-antimatter asymmetry of our universe. Chirped Zeeman EIT is an ideal optical analogue of the charge conjugation violation and universe expansion rate that satisfy the Sakharov conditions back then. We describe our experiment in warm 87Rb vapor and explain its findings in light of the quantum optics theory model. This enlarges the applicability and draws attention to the universal behavior of other physical processes that generalize the Sakharov conditions.
