Metallic nanostructures as electronic billiards for nonlinear terahertz photonics
Ihar Babushkin, Liping Shi, Ayhan Demircan +3
Optical properties of metallic nanoparticles are most often considered in terms of plasmons, the coupled states of light and quasi-free electrons. Here we predict that confinement…

Femtosecond field-driven on-chip unidirectional electronic currents in nonadiabatic tunnelling regime
Liping Shi, Ihar Babushkin, Anton Husakou +10
Recently, asymmetric plasmonic nanojunctions [Karnetzky et. al., Nature Comm. 2471, 9 (2018)] have shown promise as on-chip electronic devices to convert femtosecond optical pulses…
