The quantum vacuum as the origin of the speed of light
... The vacuum permeability μ0 , the vacuum permittivity 0 , and the speed of light in vacuum c are widely considered as being fundamental constants and their values, escaping any physical explanation, are commonly assumed to be invariant in space and time. In this paper, we propose a mechanism based u ...

A detail not develop here but important to underline is that, on the LKB group, they obtain polariton fluid without necessarily a step of condensation. The process is a quite different but the resulting state is similar. On figure ...
