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 fields suitable for use on chips.
German and Indian physicists have shown that ultra-thin two-dimensional materials such as tungsten diselenide can rotate the polarisation of visible light by several degrees at certain wavelengths under small magnetic fields suitable for use on chips.
"In the future, two-dimensional materials could become the core of optical isolators and enable on-chip integration for today's optical and future quantum optical computing and communication technologies," says Prof Rudolf Bratschitsch from the University of Münster. Prof Ashish Arora from IISER adds:"Even the bulky magnets, which are also required for optical isolators, could be replaced by atomically thin 2-D magnets.

Vibrations of granular materials: Theoretical physicists shed light on an everyday scientific mysteryCoffee beans in a jar and piles of rice or sand are examples of granular matter: materials composed of large numbers of macroscopic—rather than atomic scale—particles. Although granular matter is extremely familiar in everyday life, it represents an unexpected frontier in fundamental physics: Very little is understood about it.
