Terahertz harmonic generation across the Mott insulator-metal transition

Gulloo Lal Prajapati, Sujay Ray, Igor Ilyakov +8

We demonstrate terahertz (THz) harmonic generation across the Mott insulator-metal transition in rare-earth nickelates (RNiO${}_3$, R = rare-earth atom). The THz harmonic generation…
