Tuning terahertz beams with nanoparticles

For years, scientists have dismissed terahertz radiation. Why? There were few ways to control this line-of-sight, nonionizing radiation. However, they saw its potential. For example, it could be used for short-range, high-bandwidth ...

Hidden magnetism appears under hidden symmetry

Sometimes a good theory just needs to right materials to make it work. That's the case with recent findings by UT's physicists and their colleagues, who designed a two-dimensional magnetic system that points to the possibility ...
