Polaritonic Josephson Junctions

R. Gati and M. K. Oberthaler introduced in Ref.  the concept of Bosonic Josephson Junctions (BJJ) (?!). I hereby introduce that of Polaritonic Josephson Junctions to cover for the wealth of papers on that topic, involving polaritons.

Like all BJJ, the dynamics is that of the population difference and phase difference of the two condensates. My main input to the problem was to propose, with Amir Rahmani, to vizualize the dynamics on the Bloch sphere.
