EPFL scientists have developed a new technique that lets researchers watch, with unprecedented sensitivity, how materials ...

Polarizing film has an axis (in our diagrams we depict its direction with lines on the film), and the film allows passage of light that is oscillating parallel to the axis.

The effect of spin on the trajectories of polarized light beams has now been experimentally observed, ... Figure 1: A schematic diagram showing the trajectories of left- (in blue) ...
