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 ...

On a sunny spring day one of us (Dixon) entered the London Underground at the Mile End station on his way to Heath­row Airport. Eyeing a stranger, one of more than three million daily passengers on ...
