据我所知,目前的ESPRESSO版本不可以使用GW方法。

谢谢:)

“Another important development presently under way is an efficient implementation of GWcalculations for large systems (whose size is of the order of a few hundreds inequivalent atoms)”
这句话看上去,好像是说现在已经有GW方法了,以后的目标是要把GW方法扩充到大的体系。或许是我理解错了;)

I think it means people can DIY PAW albeit it is difficult.

I find "Generation of PAW dataset. Based on the original implementation
   by G. Fratesi with several additions by R. Mazzarello."
in /espresso-4.0.4/atomic_doc/README file

To my knowledge, Pwscf can do gw calculation with interface to SELF code, which does not publically obtain yet ..

非常感谢您的回帖:)
您说的是Yambo么?“Yambo is a FORTRAN/C code for Many-Body calculations in solid state and molecular physics. Yambo relies on the Kohn-Sham wavefunctions generated by two DFT public codes: abinit, and PWscf. The code was originally developed in the Condensed Matter Theoretical Group of the Physics Department at the University of Rome "Tor Vergata" by Andrea Marini. Previous to its release under the GPL license, yambo was known as SELF. ”

http://www.yambo-code.org/
我刚刚被JRS接收的paper中最重要的部分使用了GW的计算结果得到的(那是别人用Yambo软件做的计算)。我只是用截图的方法得到的别人的数据,而不是自己算的:/

给个Yambo简介的papar的网址;)

ESPRESSO4.05版本还不能使用GW方法,ESPRESSO5版本就会能使用了;
ESPRESSO使用PAW是有的,但赝势需要自己制造,自己测定,稍显复杂。
玩第一性原理就如看大片

QEforge 是ESPRESSO项目组设立的使用GForge组建的开发平台。 而GForge是一个基于Web的协同开发平台。它提供一组帮助你的团队进行协同开发的工具,如论坛,邮件列表等。用于创建和控制访问源代码管理库(如CVS,Subversion)的工具。GForge将自动创建一个源代码库并依据项目的角色设置进行访问控制。其它工具还包括:管理文件发布,文档管理,新闻公告,缺陷跟踪,任务管理等。

在这个网站上面可以看到很多小组正在开发新的项目,以及项目开始的时间,其中有蒙特卡洛、准粒子近似、格林函数还有含时微扰等:)从上面看,格林函数小组是2008-11-13 17:54注册的;)

ESPRESSO这样描述这个工作平台:"qe-forge provides, through a user-friendly web interface,an integrated development environment, whereby researchers can freely upload, manage and maintain their own software, while retaining full control over it, including the right of not releasing it. The services so far available include source-code management software (CVS or SVN repository), mailing lists, public forums, bug tracking facilities, download space, and wiki pages for projects’ documentation. qe-forge is expected to be the main tool by which QUANTUM ESPRESSO end users and external contributors can maintain QUANTUM ESPRESSO-related projects and make them available to the community.
