VASP+WANNIER90計(jì)算Berry Curvature 已有1人參與

大家好, 向大家請(qǐng)教一個(gè)問(wèn)題。 我看了WANNIER90的第18個(gè)turtorial,里面說(shuō)用WANNIER90計(jì)算Berry Curvature需要用最新版本的pw2wannier90代碼;換言之,這個(gè)tutorial講解的是將Quantum Espresso與WANNIER90對(duì)接時(shí),如何計(jì)算Berry Curvature。 我想請(qǐng)教下,將VASP與WANNIER90對(duì)接時(shí),是否也可以用WANNIER90計(jì)算Berry Curvature呢? 如果可以,能否麻煩大家解釋下相關(guān)的計(jì)算流程呢?或者發(fā)下計(jì)算的tutorial鏈接呢? 謝謝大家。 |

當(dāng)然是可以的,關(guān)鍵是構(gòu)造出合適的wannier函數(shù)。 發(fā)自小木蟲(chóng)Android客戶(hù)端 |

謝謝你的回復(fù)。 能麻煩你發(fā)下相關(guān)的計(jì)算步驟,或者相關(guān)的算例嗎?我是指當(dāng)用VASP與WANNIER90對(duì)接時(shí),如何計(jì)算Berry Curvature嗎? 我按照WANNIER90里的第18個(gè)tutorial,使用postw90.x計(jì)算Berry Curvature時(shí),程序回復(fù)錯(cuò)誤信息,說(shuō)沒(méi)有.spn文件。而據(jù)我所知,.spn文件是只有用Quantum Espresso與WANNIER90對(duì)接后,才會(huì)產(chǎn)生的文件。所以這18個(gè)tutorial講解的是用Quantum Espresso與WANNIER90對(duì)接時(shí),如何計(jì)算Berry Curvature。 能麻煩你發(fā)下VASP與WANNIER90對(duì)接時(shí),如何計(jì)算Berry Curvature的步驟嗎? 謝謝拉。 |

user vasp 6.4.2, see the release note: https://www.vasp.at/info/post/#NEW%20RELEASE%3a%20VASP.6.4.2 inside Visual Studio Code using the extensions view. July 20, 2023 NEW RELEASE: VASP.6.4.2 A new release of VASP is available for download now! This release differs from VASP.6.4.1 by the following changes/additions (amongst others): Fixes the following known issues: Bugs in interface to wannier90. Incorrect MLFF fast-mode predictions for some triclinic geometries. Fast-mode predictions will crash together with finite difference (IBRION=5,6). and additionally: Added a proper exit if MLFF is encounters multiple atom types with the same label. Blocking of scaLAPACK redistribution in MLFF (to reduce memory demands) was not correctly implemented. Assorted small fixes and improvements. |
