Researchers Link Light’s Spin to Electron-Positron Vortex Shape
Can light sculpt matter directly from empty space with tailored quantum properties? A modified theoretical model now reveals how manipulating laser polarisation and timing controls the formation of particle pairs, specifically, directing their spins to create either swirling ‘vortices’ or straight-line patterns. This finer level of control builds on existing theory by accounting for previously neglected interactions between photons and newly created particles.
The shape and behaviour of vortices created during electron-positron pair production are determined by the polarization of light pulses and the timing between them; both provide coherent control over vortex topologies. Circularly polarized light generates quantized vortices; linearly polarized light produces nodal lines instead. Precise control over particle creation from light is now possible through manipulation of swirling patterns, known as vortex topology, when they create electron-positron pairs. Adjusting…
