Nature Physics, Published online: 23 June 2022; doi:10.1038/s41567-022-01639-3
Both inter- and intraband transitions contribute to high-harmonic generation in solids, but their exact roles are not fully understood. Experiments with quantum dots show that enhanced intraband transitions lead to increased carrier injection and thus enhanced harmonic generation.Multimode photon blockade
