Abstract Luminescence constitutes a unique source of insight into hot carrier processes in metals, including those in plasmonic nanostructures used for sensing and energy applications. However, being weak in nature, metal luminescence remains poorly

We study the nonlinear response of collective optical resonances in linear atomic chains with metallic, semiconducting, and topologically insulating character to low-energy free electrons. The nonlinearity, which manifests in the amplitude and freque

Graphene has emerged as a promising platform to bring nonlinear quantum optics to the nanoscale, where a large intrinsic optical nonlinearity enables long-lived and actively tunable plasmon polaritons to strongly interact. Here we theoretically study

Graphene possesses a nonlinear optical response arising from its electronic dispersion. Here, the authors measure the response of graphene to an ultrafast optical field and provide an explanation of the quantum dynamics of Dirac carriers mediating th

High-harmonic generation is a nonlinear optical phenomenon that may be harnessed towards realisation of ultrafast light sources. Here, the authors theoretically show that localized plasmons in graphene nanodisks result in broadband and electrically t

The observation of high-order harmonic generation (HHG) from bulk crystals is stimulating substantial efforts to understand the involved mechanisms and their analog to the intuitive three-step recollision model of gas-phase HHG. Here we explore the r

Plasmon-assisted harmonic generation in highly-doped graphene nanoribbons is strongly enhanced by the nonlocal optical response associated with large electromagnetic field gradients in closely-spaced ribbons that have optimal size and position.
