Physicists have shown that ultra-thin two-dimensional materials such as tungsten diselenide can rotate the polarization of visible light by several degrees at certain wavelengths under small magnetic ...

Specific semiconducting materials, 100,000 times thinner than a human hair, can rotate the polarisation of visible light by several degrees under small magnetic fields. This phenomenon is known as ...

Twist a stack of atom-thin carbon sheets by just the right amount and the material stops behaving like ordinary metal or insulator. Instead, it starts acting like a peculiar kind of superconductor ...
