Nonadiabatic nonlinear optics and quantum geometry—Application to the twisted Schwinger effect

S Takayoshi, J Wu, T Oka - SciPost Physics, 2021 - scipost.org
We study the tunneling mechanism of nonlinear optical processes in solids induced by
strong coherent laser fields. The theory is based on an extension of the Landau-Zener …

[图书][B] Symmetry Breaking and Harmonic Generation in Metasurfaces and 2-Dimensional Materials

JS Ginsberg - 2021 - search.proquest.com
A strong argument can be made that physics is, at its core, the study of symmetries.
Nonlinear optics is certainly no exception, with an enormous number of distinct processes …
