Non-perturbative high-harmonic generation in the three-dimensional Dirac semimetal CdAs
Sergey Kovalev, Renato M. A. Dantas, Semyon Germanskiy +12
Harmonic generation is a general characteristic of driven nonlinear systems, and serves as an efficient tool for investigating the fundamental principles that govern the ultrafast…
