`Our resonant rectifiers inherently act as second-order harmonic generators, rectifying currents without the presence of a potential barrier. Particle-in-cell simulations reveal that femtosecond electron-surface scattering plays a critical role in this process.`

Researchers demonstrate a method for generating #terahertz vortices with continuously tunable topological charges. This advance may enable the manipulation of molecular physical processes, including rotational and vibrational energy levels. Read more in #APNexus - www.spiedigitallibra...

What will 6G networks look like? Many service providers hope to hit speeds into the range of a terabit or more. But...

If we want to boost bandwidth to such extremes, many potential bottlenecks must be addressed.

And here's a fun one you've probably never thought about. You know how the backbone of the Internet is built on fiber-optics?

Reading magnetic states faster – in far infrared: Team of #HZDR and TU Dortmund University provides proof of feasibility of ultrafast data storage. Instead of electrical pulses, they use ultrashort #terahertz light pulses, enabling the read-out of magnetic structures within #picoseconds.

"Here, we show that chirality of either handedness can be induced in the nonchiral piezoelectric material boron phosphate..by irradiation with terahertz pulses. Resonant excitation of either one of two orthogonal, degenerate vibrational modes determines the sign of the induced chiral order parameter... Our findings offer new prospects for the control of out-of-equilibrium quantum phenomena in complex materials."
