Story summary

Researchers have manipulated electron motion at the femtosecond timescale by using light to control quantum materials, a study published in Nature Communications.
A team led by Prof. Miriam Serena Vitiello has achieved high-order harmonic generation in topological insulators, producing both even and odd terahertz frequencies.
The developments pave the way for compact terahertz light sources and enhanced optoelectronic technologies.
