The system is shown to exhibit a Dirac-like spectrum for light-matter quasi-particles with multiple dark-states, termed spinor slow-light polaritons (SSP). They posses an \"effective speed of light\" given by the group-velocity of slow-light, and can be made massive by inducing a small two-photon detuning. Control of the two-photon detuning can be used to locally vary the mass including a sign flip. This allows e.g. th","authors_text":"G. Juzeliunas, J. Otterbach, J. Ruseckas, M. Fleischhauer, R.G.
