We propose the development and implementation of an advanced material model for the description of the ultrafast nonlinear optical response of metallic nanostructures. This model comprises a quantum hydrodynamic treatment of the conduction electrons in metals that will eventually be coupled to a particle-in-cell approach in order to realize a hybrid theoretical and computational framework. In cooperation with experimental partners, this framework will be applied to nonlinear wave mixing phenomena, ponderomotive nonlinearities, and nonlinear photoemission processes that may be controlled via tailored beams.

我们建议开发和实施一种先进的材料模型来描述金属纳米结构的超快非线性光学响应。该模型包括对金属中传导电子的量子流体动力学处理，最终将与细胞内粒子方法相结合，以实现混合理论和计算框架。与实验伙伴合作，该框架将应用于非线性波混合现象、有质动力非线性和可通过定制光束控制的非线性光电发射过程。
