Query: Fast-Responding Property of Electromagnetically Induced Transparency in
  Rydberg Atoms   We investigate the transient optical response property of an
electromagnetically induced transparency (EIT) in a cold Rydberg atomic gas. We
show that both the transient behavior and the steady-state EIT spectrum of the
system depend strongly on Rydberg interaction. Especially, the response speed
of the Rydberg-EIT can be five-times faster (and even higher) than the
conventional EIT without the Rydberg interaction. For comparison, two different
theoretical approaches (i.e. two-atom model and many-atom model) are
considered, revealing that Rydberg blockade effect plays a significant role for
increasing the response speed of the Rydberg-EIT. The fast-responding
Rydberg-EIT by using the strong, tunable Rydberg interaction uncovered here is
not only helpful for enhancing the understanding of the many-body dynamics of
Rydberg atoms but also useful for practical applications in quantum information
processing by using Rydberg atoms.
