Physicists have engineered light to drift sideways in discrete, quantized steps inside a fiber-optic loop, reproducing a signature behavior of the quantum Hall effect without electrons, magnetic ...

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 ...

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 ...
