Axil,
What happens to an electron that is in free space when it encounters a photon? One could easily imagine that it merely changes momentum and energy relative to our observation frame, but then you have to ask about the issue of time. So, what does a free space electron that absorbs a photon behave like as compared to a free space electron that has more energy than one at rest? Can you tell them apart by any measurement? Is there any reason to expect the now more energetic electron to radiate when it is moving at a greater, constant speed?

Because that is what Wikipedia says. http://en.wikipedia.org/wiki/Polariton “The polariton is a bosonic quasiparticle, and should not be confused with the polaron, a fermionic one, e.g. an electron plus attached phonon cloud.” But your confusion is on-target. The spin of the polariton might well come from the dipole that makes it up. Electrons emit and adsorbed photons all the time and they still have ½ spin. But your confusion has inspired burgeoning confusion on my part because the article says that coupling times increases the probability of BEC formation. The article says “While strong optical coupling in the single-quantum limit provides tremendous possibilities for quantum information processing through quantum electrodynamic effects, (4, 5) it is through the use of strong optical coupling in many particle systems that phenomena such as Bose-Einstein condensation in the solid-state (6, 7) and low-threshold polariton lasing and light emission (8, 9) have been discovered.” Also “Additional surface passivation that preserves the polaritonic nature of the excitations at small nanowire diameters (22) allows us to push the observed vacuum Rabi splitting to values of up to 200 meV in comparison to bulk values of 82 meV. These results provide new avenues to achieve very high coupling strengths (beyond bulk) potentially enabling application of exciting phenomena such as Bose-Einstein condensation of polaritons,” In quantum electrodymanics (QED), coupling is another name for charge. In QED, the photon is the charge carrier. Also in this confusing statement, could they be saying that the charge of the polariton is greater than the electron? But in this paper it looks like the authors are using the term in another way related to photon coupling. I could be making bad inferences. The photon coupling decreases the mass of the polariton by a factor of 10,000. This could be the reason for the increase in BEC formation probability. Charge of the polariton cannot be 16 times more powerful in a polariton than in an electron; Can it? I am learning this stuff also; I need to increase my proficiency in QED, because the devil is in the details. Enlightenment is welcome for all those who are kind enough to grant it.
