Terahertz spectroscopy of collective charge density wave dynamics at the atomic scale

S. Sheng, M. Abdo, et al.

This groundbreaking research by Shaoxiang Sheng and colleagues utilizes terahertz pump-probe spectroscopy to explore ultrafast charge density wave dynamics in 2H-NbSe₂ at atomic-scale resolution. By uncovering how atomic impurities influence these oscillations, this study offers fascinating insights into the intricate dance of electron density modulations.
