Entanglement features on the dynamics of quantum polariton vortex.

Indivisible excitations of a quantum system are the fundamental bricks of physical behaviour. In essential respects, they allow interpreting chance as the fundamental feature of quantum realism. This is the framework in which quantized vortices must be tackled, which are usually studied between a mean-field or coherent approach. Hence, we use an approach to analyse, in a general way, a quantized vortex under quantum coupling, i.e.,  indivisible excitation exchange. This fully quantized picture enables the system to undergo richer dynamics; the vortex core and its phase singularity follow a far from a plain family of trajectories. In this approach, the state operator's superposition principle allows light and matter entanglement.
