剛剛發(fā)現(xiàn),同學(xué)使用的計(jì)算自由能的方法是比著MedeA中一個(gè)組件GIBBS在CPC上發(fā)表的文章,自己做的excel計(jì)算的,中間在擬合及數(shù)據(jù)處理上都存在一定問題。 但是突然發(fā)現(xiàn)CPC上直接提供GIBBS程序的源碼包,并且?guī)в芯幾g好的二進(jìn)制文件,只要能下載CPC文章的就可以下載該包。 該包只適用于Linux和UNIX系統(tǒng),這對(duì)于使用PWscf的來(lái)說(shuō)足夠了。 軟件使用非常簡(jiǎn)單,完全可以與pw.x聯(lián)合起來(lái)使用,對(duì)于不超過(guò)10個(gè)原子的體系,估計(jì)在很普通的電腦上,都能半小時(shí)內(nèi)得到一批熱力學(xué)數(shù)據(jù)。 GIBBS軟件的計(jì)算精度不清楚,懶得找文章測(cè)試了~有興趣的可以試一下~ CPC的含義:Computer Physics Communications,地址:http://www.elsevier.com/locate/cpc |

今天受到了Paolo在mailist里面的信,給大家看看,了解一下新功能。Paolo私下告訴我下一步Pwscf發(fā)展的重點(diǎn)就是分子動(dòng)力學(xué),到時(shí)候會(huì)把最近的分子動(dòng)力學(xué)進(jìn)展比如langevin molecular dynamics加進(jìn)去。 Version 4.3 of the Quantum ESPRESSO distribution is available for download from the website http://www.quantum-espresso.org . This release contains the following improvements over previous versions: * vdW-DF - Dispersion interactions (van der Waals) with nonlocal functional in PWscf (Brian Kolb, Timo Thonhauser, Riccardo Sabatini, SdG) * New package TDDFPT for calculations of spectra using Time-Dependent Density-Functional Perturbation Theory (SB, Ralph Gebauer, Baris Malcioglu, Dario Rocca, Brent Walker) * Additions to projwfc: k-resolved DOS, LDOS integrated in selected real-space regions * Constant-volume variable-cell optimization * Non-colinear and spin-orbit PAW * CP only, experimental: parallelization over Kohn-Sham states * CP only, experimental: penalty functional technique in DFT+U calculations Note the following major change: * code pw.x no longer performs NEB calculations. NEB is now computed by a separate code, NEB/neb.x . NEB-specific variables are no longer read by pw.x; they are read by neb.x after all pw.x variables * NEB for cp.x no longer available For other minor improvements, changes, bug fixes, see file Doc/release-notes Everybody who is using the Quantum-ESPRESSO distribution is encouraged to upgrade and to report problems to the mailing list.
