Abstract
We put forth and discuss in detail a scheme to achieve Bose-Einstein condensation of stationary-light dark-state polaritons with dipolar interaction. To this end we introduce a diamondlike coupling scheme in a vapor of Rydberg atoms under the frozen gas approximation. To determine the system's dynamics we employ normal modes and identify the dark-state polariton corresponding to one of the modes. We show that in contrast to atomic dipolar ultracold vapors, the dark-state polariton Bose-Einstein condensates proposed here can be stable for a negative dipolar interaction constant.
