circularly polarized light SHG
Posted: Tue Jul 07, 2026 10:55 am
Dear all，
For a two-dimensional magnetic system that includes SOC, I want to calculate the SHG components under left-handed and right-handed circularly polarized light.(I am currently using version 2.0.0 of Lumen)
1、How should we set up for electric fields 1 and 2 in nonlinear calculations ?
2、In the "fixsymm.in" file, what should be done when removing symmetry?
Best,
