【求助】VASP計(jì)算光學(xué)性質(zhì)時(shí)的GW方法(RPA, no local field effects) 已有4人參與
|

按通常設(shè)置 LOPTICS = .TRUE. LRPA = .TRUE. LEPSILONG = .FALSE. ... ... 計(jì)算出來(lái)的OUTCAR中會(huì)給出介電函數(shù),然而總有一句(RPA, no local field effects),我查了手冊(cè),有一句這樣的話 “Finally, the GW routine is the only routine capable to include local field effects for the frequency dependent dielectric function.”(http://cms.mpi.univie.ac.at/vasp ... lectric_matrix.html) 意思說(shuō)GW方法是在介電函數(shù)中包含local field effects 的唯一方法,我想試試包含這種影響的話對(duì)計(jì)算結(jié)果會(huì)有什么影響,但用GW方法(先自洽DFT,再自洽HF,再非自洽GW),結(jié)果中還是有(RPA, no local field effects),沒有達(dá)到手冊(cè)上說(shuō)的效果 The imaginary and real part of frequency dependent dielectric function is always determined by the GW routine. It can be conveniently grepped from the file using the command (note two blanks between the two words) grep " dielectric constant" OUTCAR The first value is the frequency (in eV) and the other two are the real and imaginary part of the trace of the dielectric matrix. Note that two sets can be found on the OUTCAR file. The first one corresponds to the head of the microscopic dielectric matrix (and therefore does not include local field effects), whereas the second one is the inverse of the dielectric matrix with local field effects included in the random phase approximation or density functional approximation (depending on LRPA). 是不是因?yàn)榈谌竭是應(yīng)該自洽算(ICHARG = 2)? 論壇上關(guān)于GW方法計(jì)算光學(xué)性質(zhì)的內(nèi)容挺少的,拋磚引玉,大家發(fā)表意見吧~ |
