<b>Subject:</b> [QE-users] [SPAM] Calculate optical properties with Ultrasoft PPs</font>
<div> </div>
</div>
<div>Dear QE users,
<div><br>
</div>
<div>I want to calculate optical properties (dielectric function, refractive index, conductivity, reflectivity, and loss function) of a cristal. Most tutorials show how to do it using epsilon.x. </div>
<div><br>
</div>
<div>However, is there another way using TD-DFT with some of the turbo-packages? What can I do to obtain these properties?</div>
<div><br>
</div>
<div>Thanks for your help.</div>
