Dynamics of a quantum polariton vortex: Low excitation scenario

TL;DR

This paper explores the quantum dynamics of polariton vortices at low excitation levels, revealing richer behaviors and quantum correlations that differ from classical vortex phenomena, thus bridging quantum and classical vortex dynamics.

Contribution

It introduces a fully quantized model for polariton vortices, uncovering new quantum trajectories and correlations not captured by mean-field approaches.

Findings

Quantum correlations lead to non-circular vortex trajectories.

A criterion differentiates quantum from classical vortex behavior.

Quantum vortex dynamics exhibit richer, more complex trajectories.

Abstract

Quantum vorticity in polariton systems has been traditionally investigated within the frame of many-body phenomena under the mean-field or coherent approaches. In the present work, we show that the fully quantized picture describes richer dynamics for the vortex core at the quantum coupling limit, where two systems exchange an indivisible excitation. The quantum correlations intrinsic to our formalism account for the emergence of a family of trajectories that differ from the circular paths known in macroscopic vorticity phenomena. These results indicate that there exists a criterion to differentiate the behavior at the edge between the quantum and classical polariton vortex dynamics.
