I am using Yambo code for optical properties using GW+BSE, I am able to calculate the imaginary part of the dielectric constant following https://www.yambo-code.eu/wiki/index.ph ... al_systems
Can anyone tell how to calculate dielectric constant in different directions, x and y?

Dear arashita,

please follow the rule of the forum:
1. Choose the appropriate subforum. The question you posted is not appropriate for the Job offers and Announcements subforum. It is important that questions and answers are searchable for all the users.

2. Sign your post with your name and affiliation, you can do once for all by filling the signature in your user profile.

The polarization is indicated in input by the variable: 1 | 0 | 0

and

0 |1 | 0

provides respectively the x and y direction.

It can be useful to have a look at the Yambo cheatsheet for the meaning of variables.

Best,
Daniele
