Excitons in second harmonic generation

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
