It might be easier to track tiny particles in the future - even when they hurtle along with the speed of a rifle bullet. This is thanks to researchers working with Christoph Marquardt and Gerd Leuchs at the Max Planck Institute for the Science of Light, who have discovered that these particles can be tracked with a radially polarized laser beam. In radially polarized light, the oscillation planes of the light waves arrange themselves like the spokes of a wheel. When the researchers cause a parti...
