We propose and generate a class of structured light fulfilling the mathematical form SU(2) coherent state based on set circular Airy vortex modes. Such wave packets possess strong focus with both radial angular self-accelerations, which exploit more general 3D inhomogeneous velocity control global spatial symmetry multilayer rotation akin to galactic kinematics, termed galaxy waves. Galaxy wave...

We introduce Gilmore-Perelomov coherent states for non-unitary representations of non-compact groups, and discuss the main similarities and differences with respect to ordinary unitary Gilmore-Perelomov coherent states. The example of coherent states for the non-unitary finite dimensional representations of SU(1, 1) is considered and they are used to describe the propagation of light in coupled...
