The linear energy dispersion of graphene electrons leads to a strongly nonlinear
electromagnetic response of this material. We develop a general quantum theory of the third …

The nonlinear optical (NLO) materials are playing a crucial role in almost all aspects of
photonics including imaging frequency, manipulation, photon generation, transmission and …

Saturable absorption is a nonperturbative nonlinear optical phenomenon that plays a pivotal
role in the generation of ultrafast light pulses. Here we show that this effect emerges in …

We present a practical scheme to separate the contributions of the electric quadrupole-like
