Ultrafast two-photon emission in a doped semiconductor thin film
Futai Hu, Liu Li, Yuan Liu +3
As a high-order quantum transition, two-photon emission has an extremely low occurrence rate compared to one-photon emission, thus having been considered a forbidden process. Here,…

High-harmonic generation from an epsilon-near-zero material
Yuanmu Yang, Jian Lu, Alejandro Manjavacas +7
High-harmonic generation (HHG) from a compact, solid-state medium is highly desirable for applications such as coherent attosecond pulse generation and extreme ultra-violet (EUV) s…
