Topological materials produce electron states that can be very interesting for technical applications, but it is extremely difficult to identify these materials and their associated electronic states. A 'crystal' made of light waves can now be used to deliberately drive the system out of equilibrium. By switching between simple and complicated states, the system reveals whether or not it has topologically interesting states.

Researchers have created a graphene-based terahertz detector. Their device doubles as a sensitive detector and a spectrometer operating in the terahertz range, and it's also a tool for studying plasmons in two-dimensional materials. All of these things existed before, but they took up a whole optical table. Researchers packed the same functionality into a dozen micrometers.
