Abstract

We study in detail the interesting dynamical symmetry and its applications in general many-level and many-ensemble atomic systems with electromagnetically induced transparency (EIT). By discovering the symmetrical Lie group of various atomic systems, the novel applications to quantum memory and quantum entanglement between photons or atomic ensembles are investigated.
