Detuning control of Rabi vortex oscillations in light matter coupling
arXiv:1901.10144 · doi:10.1103/PhysRevB.100.094310
Abstract
We study analytically the dynamics of vortices in strongly coupled exciton--photon fields in the presence of energy detuning. We derive equations for the vortex core velocity and mass, where they mainly depend on Rabi coupling and the relative distance between the vortex cores in photon and exciton fields, and as the result core positions oscillate in each field. We use Magnus force balanced with a Rabi induced force to show that the core of the vortex behaves as an inertial-like particle. Our analysis reveals that the core is lighter at periphery of the beam and therefore it is faster at that region. While detuning induces oscillations in population imbalance of components through relative phase between coupled fields, in the presence of topological charges detuning can control the orbital dynamics of the cores. Namely, it brings the vortex core to move on larger or smaller orbits with different velocities, and changes angular momentum and energy content of vortex field.
