Abstract

This Letter establishes a Floquet engineering framework in which coherent high frequency light with a time dependent amplitude can be used to parametrically excite and amplify THz plasmons, mirror plasmonic wave packets in time, and generate momentum-gapped plasmonic band structures, entangled plasmon pairs, and THz radiation in two dimensional Dirac systems. Our results show how low frequency plasmons can be coherently excited and manipulated without the need for THz light.

光控太赫兹等离子体时变介质：动量间隙、纠缠等离子体对和脉冲诱导时间反转

本文建立了一个Floquet工程框架，在该框架中，具有时间依赖性振幅的相干高频光可以用于参数化激发和放大太赫兹等离子体，在时间上镜像等离子体波包，并在二维狄拉克系统中产生动量间隙等离子体带结构，纠缠等离子体对和太赫兹辐射。我们的研究结果显示了低频等离子体如何在不需要太赫兹光的情况下被相干激发和操纵。2024年由美国物理学会出版
