Physicists have forced light to behave like electrons trapped in a magnetic field, reproducing the quantum Hall effect with photons for the first time. The experiment, carried out on an optical fiber ...

Physicists have for the first time observed light drifting sideways in discrete, quantized steps, reproducing a quantum Hall effect that was previously seen only in electrons confined to ultra-thin ...

Empty space, despite how we think of it, may not be as empty as we assume. Although we cannot detect the virtual particles present in empty space, their presence is necessary to predict, ...
