Polaritonic Josephson Junctions
R. Gati and M. K. Oberthaler introduced in Ref. [1] 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.[2]
Theory:
- Coherent dynamics and parametric instabilities of microcavity polaritons in double-well systems. D. Sarchi, I. Carusotto, M. Wouters and V. Savona in Phys. Rev. B 77:125324 (2008).
- Synchronized and desynchronized phases of coupled nonequilibrium exciton-polariton condensates. M. Wouters in Phys. Rev. B 77:121302(R) (2008).
- Josephson effects in condensates of excitons and exciton polaritons. I. A. Shelykh, D. D. Solnyshkov, G. Pavlovic and G. Malpuech in Phys. Rev. B 78:041302(R) (2008).
- Polaritonic Rabi and Josephson oscillations. A. Rahmani and F.P. Laussy in Sci. Rep. 6:28930 (2016).
Experiments:
- Coherent Oscillations in an Exciton-Polariton Josephson Junction. K. G. Lagoudakis, B. Pietka, M. Wouters, R. André and B. Deveaud-Plédran in Phys. Rev. Lett. 105:120403 (2010).
