Excitons in second harmonic generation
![](https://www.attaccalite.com/wp-content/uploads/2014/01/exciton.png)
Together with Myrta Gruning we just submitted a new paper on second harmonic generation(SHG) in two-dimensional materials, h-BN and MoS2. We calculated the SHG using a real-time approach that we recently developed. We included both local field effects and electron-hole interaction at the level of screened exchange , without any additional approximation. Our approch is… Read More
