calculation of the absorption spectra: control of the polarization

[sabrine]

Dear developers

I would like to calculate the absorption spectra for left and right orientation of circular polarization of the pumb laser for 2d materials.

Does Yambo calculate /control the circularly polarized absorption for 2D materials .


Thanks

Yambo can compute epsilon_xx and epsilon_xy. (or alpha_xx and alpha_xy)
From that you can extract the absorption of circularly polarized light.

Just set

Code: Select all

BSEprop="abs kerr"

in your bse run.

You will get two files:
- .epsilon or .alpha for the diagonal components
- .off or .beta for the off-diagonal components
