Terahertz waves are being intensely studied by researchers around the world seeking to understand the “terahertz gap.” Terahertz waves have a specific frequency that put them somewhere between microwaves and infrared light. This range is referred to as a “gap” because much remains unknown about these waves. In fact, it was only relatively recently that researchers were able to develop the technology to generate them.

Weyl magnets — a type of topological material — have been shown to generate a huge anomalous Hall effect that make them suitable for generating terahertz waves.

Researchers create the world's strongest ionizing terahertz radiationTerahertz waves, known as non-ionizing radiation, can turn into ionization radiation when sufficiently many terahertz photons are focused in space and time. A team led by scientists in Korea and the U.S. has created the world's most intense terahertz pulses that can instantaneously ionize atoms and molecules and convert them into plasma.
