文摘Vortices are among nature’s most elegant manifestations of order within motion.They appear wherever flow meets rotation—from the microscopic whirlpools of quantum fluids and living cells to the cosmic spirals of galaxies.Across these vastly different scales,the essence remains the same:a circulating current wrapped around a singularity.In both classical and quantum realms,vortices carrying orbital angular momentum(OAM)have emerged as a unifying concept,realized with photons,electrons,and even cold atoms and molecules.These quantized whirlpools of phase have illuminated fundamental aspects of angular momentum,topology,and coherence,while driving applications in optical manipulation,communications,and quantum information.
