Quantum Control With Light Paves Way For Ultra-Fast Computers

control

Terahertz light can control some of the essential quantum properties of superconducting states, report researchers. Jigang Wang patiently explains his latest discovery in quantum control that could lead to superfast computing based on quantum mechanics: He mentions light-induced superconductivity without energy gap. He brings up forbidden supercurrent quantum beats. And he mentions terahertz-speed symmetry breaking. …

Photonic Crystals Self-Assembled From Colloidal Particles

Pyrochlore

Scientists have worked for decades to get colloidal spheres to arrange themselves in sparser lattices, which would unleash potentially valuable optical properties. The structures, called photonic crystals, could increase the efficiency of lasers, make optical components even smaller, and increase engineers’ ability to control the flow of light. Now, New York University researchers report a …

Time Scale Stretching For Improving Prediction Of Extreme Events

stretching time scales

A technique currently applied in the field of photonics could help predict rogue wave events on the ocean surface, along with other extreme natural phenomena. Stretching time scales to explore extreme events in nature is possible, according to a team from the Institut FEMTO-ST, which used an innovative measurement technique enabling the capture of such …

Photo-induced Force Microscopy Measures Nanoparticles With Light

Atomic Force Microscope

A new technique called “photo-induced force microscopy,” which probes the optical properties of nanomaterials by measuring the physical force imparted by light, is being tested by scientists at Rice University. Isabell Thomann’s primary research centers on using nanoparticles and sunlight to reduce the carbon footprint of power plants. A major focus is photocatalysis, a class …
