<blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">It's so exciting to see the new release of espresso-4.1, and a lot of new parts in<br>the code. But i would like to know if it includes the parts of TDDFT and GW? They<br>
have been discussed a lot before, and expected to be done soon?</blockquote>

<div>As I only use 4.0.5, I do not know whether QE 4.1can perform GW and TDDFT calculation.</div>
<div>If you want to do GW and TDDFT righti now, you can try Yambo.</div>
<div>
<p align="justify">Yambo is a FORTRAN/C code for Many-Body calculations in solid state and molecular physics. Yambo can take PWscf output files as its input file and do GW and TDDFT calculation. And Yambo is free. You can find it here <a href="http://www.yambo-code.org/index.php">http://www.yambo-code.org/index.php</a> .</p>

<div>From you address, I know you are Chinese. You can visit <a href="http://blog.sina.com.cn/nkasir">blog.sina.com.cn/nkasir</a> to find some information about Yambo installaiton.</div>
