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 forced light to behave like electrons trapped in a magnetic field, producing a quantized sideways drift that had never been observed in photons before. The experiment, carried out on ...

Hall effect sensors are everywhere right now. Keyboards, game controllers, and DIY kits use them for more precise inputs. But with any newly popular device, it can be easy to immediately jump onto the ...
