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 ...

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 ...

Quantum mechanics — the breakthrough physics theory that paved the way to our modern understanding of atoms, molecules and light — is turning 100 years old next year. During that time, the theory has ...
