Abstract

Challenge to control the quantum states of matter via light have been at the forefront of modern research on driven quantum matter. We explore the imprinting effects of structured light on superconductors, demonstrating how the quantum numbers of light-specifically spin angular momentum, orbital angular momentum, and radial order-can be transferred to the superconducting order parameter and control vortex dynamics. Using Laguerre-Gaussian beams, we show that by tuning the quantum numbers and the amplitude of the electric field, it is possible to manipulate a variety of vortex behaviors, including breathing vortex pairs, braiding vortex pairs, vortex droplets, supervortices, and swirling 2D vortex rings. More complex structure of vortex-clusters, such as vortex-flake structures, and standing wave motions, also emerge under specific quantum numbers. These results demonstrate the ability to control SC vortex motion and phase structures through structured light, offering potential applications in quantum fluids and optical control of superconducting states. Our findings present a diagram that links light's quantum numbers to the resulting SC vortex behaviors, highlighting the capacity of light to transfer its symmetry onto superconducting condensates. We point that this approach represents the extension of the printing to quantum printing by light in a coherent state of electrons.
