Highly efficient terahertz generation using 3D Dirac semimetals

It is shown that three-dimensional Dirac semimetals are promising candidates for highly efficient optical-to-terahertz conversion due to their extreme optical nonlinearities. In particular, it is predicted that the conversion efficiency of (Formula presented.) exceeds typical materials like (Formula...
