Persuading light to mix it up with matter


MIT News - 1 minggu yang lalu
Researchers at MIT have succeeded in producing and measuring a coupling of photons and electrons on the surface of an unusual type of material called a topological insulator. This type of coupling had been predicted by theorists, but never observed. The researchers suggest that this finding could lead to the creation of materials whose electronic properties could be “tuned” in real time simply by shining precise laser beams at them. The work “opens up a new avenue for optical manipulation of quantum states of matter,” says Nuh Gedik, the Lawrence C. (1944) and Sarah W. Biedenharn As... lainnya »
