TL;DR: The quantum-mechanical simulations of the plasmon-enhanced optical response of nanographene reveal this material as an ideal platform for the development of electrically tunable nonlinear optical nanodevices.

TL;DR: In this paper, a semianalytical nonperturburbative single-particle approach is proposed to describe electron dynamics in the atomically thin material using the two-dimensional Dirac equation for massless Dirac fermions, which is recast in the form of generalized Bloch equations.

TL;DR: In this article, the instantaneous response of graphene to ultrafast optical fields is investigated, elucidating the role of hot carriers on sub-100-fs timescales, and an intuitive picture is given for the carrier trajectories in response to the optical-field polarization state, which may also apply to surface states in topological insulators with similar Dirac cone dispersion relations.

TL;DR: These results support the strong potential of nanostructured graphene as a robust, electrically tunable platform for high-harmonic generation and demonstrate through rigorous time-domain simulations that the synergistic combination of strong plasmonic near-field enhancement and a pronounced intrinsic nonlinearity result in efficient broadband high- Harmonic generation within a single material.

TL;DR: In this paper, the dipole-dipole interaction and energy transfer in a hybrid system consisting of a quantum dot and graphene nanodisk embedded in a nonlinear photonic crystal was investigated.
