[交流] 【分享】ESPRESSO小组刚写的总结性文章 已有3人参与

6月25号ESPRESSO刚刚写好的文章,投到Journal of physics:Condenced Matter了,还没有正式发表呢;P    大家先睹为快吧;)
     估计以后用ESPRESSO发文章,就需要引这篇文献了;)

申请加精;P

大家看完后有什么感想,有空来聊聊吧;P

熟悉ESPRESSO的朋友都知道赝势文件的后缀是UPF
我以前以为UPF是ultro-soft-pseudo的缩写
所以一直很纳闷为什么后缀是UPF的赝势中既有超软,又有模守恒

今天看这篇文献,终于知道了UPF的全称是
Unified Pseudopotential File (UPF).

ESPRESSO如是说:“Another problem affecting interoperability of PW-PP codes is the availability of data files containing atomic PP’s — one of the basic ingredients of the calculation. There are many different types of PP’s, many different codes generating PP’s (see e.g. Ref [75, 76, 77]), each one with its own format. Again, the choice has fallen on a simple solution that makes it easy to write converters from and to the format used by QUANTUM ESPRESSO. Each atomic PP is contained in a formatted file (efficiency is not an issue here), described by a XML-like syntax. The resulting format has been named Unified Pseudopotential File (UPF). Several converters from other formats to the UPF format are available in QUANTUM ESPRESSO.”

我先起个头:)

摘要的第一句是:QUANTUM ESPRESSO is an integrated suite of computer codes for electronic-structure calculations and materials modeling, based on density-functional theory, plane waves, and pseudopotentials (norm-conserving, ultrasoft, and projector-augmented wave).


可是我从没听说,在它提供的赝势库中也没见过ESPRESSO使用过PAW?

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