Third-order terahertz optical response of graphene in the presence of Rabi Oscillations
Sawsan Daws, David R. Andersen
Graphene has been shown to exhibit a nonlinear response due to its unique band structure. In this paper, we study the terahertz (THz) response metallic armchair graphene nanoribbon…

Terahertz continuum generation in the LCS lattice
Qiutong Jin, David R. Andersen
Rabi oscillations in two-level Dirac systems have been shown to alter the frequency content of the system's nonlinear response. In particular, when considering Rabi oscillations in…

First-principles study of the terahertz third-order nonlinear response of metallic armchair graphene nanoribbons
Yichao Wang, David R. Andersen
We compute the terahertz third-order nonlinear conductance of metallic armchair graphene nanoribbons using time-dependent perturbation theory. Significant enhancement of the intrin…
