Researchers monitor electron behavior during chemical reactions for the first time

Using laser pulses and supercomputing simulations, researchers observe electrons' motions in real time.

Quantum tricks to unveil the secrets of topological materials

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.

Strong interactions produce a dance between light and sound

Light and high-frequency acoustic sound waves in a tiny glass structure can strongly couple to one another and perform a dance in step.

New T-wave detector uses waves of the electronic sea in graphene

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.
