Temporal shaping and time varying orbital angular momentum of displaced vortices
Fazele Hosseini, Mohammad A. Sadeghzadeh, Amir Rahmani +2
The fundamental mode of rotation in quantum fluids is given by a vortex, whose quantized value yields the orbital angular momentum (OAM) per particle. If the vortex is displaced (o…

Detuning control of Rabi vortex oscillations in light matter coupling
Amir Rahmani
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 m…
