[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

ESPRESSO下一步的发展重点在于: 一、激发态,二、GW方法(应该是格林函数方法)。我对第二个最为期待:)
        Abinit 软件已经可以用GW方法计算激发态了,目前的ESPRESSO版本可以使用GW方法计算么?这个我不清楚,知道的给个答案:)
         Many of the soon-to-come additions will deal with excited-state calculations within timedependent DFT (TDDFT [158, 159]) and/or many-body perturbation theory [160]. A new approach to the calculation of optical spectra within TDDFT has been recently developed [161], based on a finite-frequency generalization of densityfunctional perturbation theory [54, 55], and implemented in QUANTUM ESPRESSO. 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) [162]. The implementation of efficient algorithms for calculating correlation energies at the RPA level is also presently under way [163, 164, 165]. It is foreseen that by the time this paper will appear, many of these developments will be publicly released.

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.
