Humans typically blink 4 times per second, equivalent to a frequency of 4 Hz. Blinking at a rate of 1 billion times per second, or 1 GHz, is not possible for a human being. But this is the current ...

Among researchers, this is called the terahertz gap. In recent years, it was discovered that light sources in this frequency band can be applied to a wide range of areas such as ultra-high-speed ...

Chirality refers to objects that cannot be superimposed to their mirror images through any combination of rotations or translations, much like the ...

With new laser sources and detectors coming onto the market, terahertz imaging is starting ... pulses generated can be used like high-frequency radar to image the profile, the internal structure ...

Emission is then obtained at the difference frequency of the lasers, and this can be engineered to fall in the terahertz range ... dehydration behaviour, as high-quality spectra from many points ...

Scientists from the (MPSD) and MIT have achieved a groundbreaking feat — creating a stable, long-lasting magnetic state in an antiferromagnetic material using only light. This discovery could lead to ...

Physicists in the US, Europe and Korea have produced a long-lasting light-driven magnetic state in an antiferromagnetic material for the first time. While their project started out as a fundamental ...

University of Ottawa researchers enhance THz wave frequency conversion in graphene, paving the way for advanced wireless ...

Researchers developed innovative methods to enhance frequency conversion of terahertz (THz) waves in graphene-based ...

Chirality refers to objects that cannot be superimposed onto their mirror images through any combination of rotations or translations, much like the distinct left and right hands of a human. In chiral ...
