Hi, This latest announcement on the development of something resembling a BEC using polaritons seems interesting: http://physorg.com/news98645866.html http://physicsweb.org/articles/news/11/5/17/1 So I'd like to know what the implications of this development are. Could this "polariton BEC" be used in further experiments to probe matter? Could it be used as a springboard to make more important discoveries, and if so, how? Are there any possible practical applications of this development? The announcement says that this "polariton BEC" could generate laser output in a more energy-efficient way than lasers achieved through conventional population inversion of electrons. The "polariton BEC" can apparently also be achieved at temperatures somewhere between liquid nitrogen and room temperature, which sounds more cost-effective. Could it perhaps then be used to generate high-energy lasers more efficiently, and thus be of assistance in applications like laser-confinement fusion, for example? Or maybe directed energy weapons? What are the limitations and constraints on this technology?
