We consider collective spontaneous emission from an ensemble of N identical two-level atoms prepared by absorption of a single photon-a.k.a. single photon Dicke superradiance. We discuss dynamical properties of superradiance for small (R << ) and large (R >> ) atomic cloud. Moreover, we address the effects of virtual processes on collective decay rate and Lamb shift. It turns out that virtual processes lead to relatively small yet interesting effects on the time evolution of a rapidly decaying state. However, such processes substantially modify the dynamics of trapped states by bringing in new channels of decay. 2010 Taylor & Francis.
