Here is a daily log for Daria Satco from 2018.9.4 to 2018.11.29 in Saito Lab in Tohoku Univ. #contents *Daily schedule (tentative) [#j707648f] - 09:00-11:00 Finishing/continuing any work from previous day - 11:00-12:00 Discussion with Nugraha-san - 12:00-13:00 Lunch - 13:00-15:00 Prepare for daily report presentation - 15:00-16:00 Meeting with Saito-sensei - 16:00-17:30 Start working on work for tomorrow's presentation and updating Pukiwiki *Goal of the project [#adbe3b51] - To explain the origin of new peak in doped CNT optical spectra. *Questions and Answers [#k8467fec] This section is for posting questions from Jakob-san and answers from other group members. - Please list here with some simple reasons or details. - For every problem, give a tag double asterisks (**) in the code so that it will appear in the table of contents. - For the answer, give a tag triple asterisks (***) in the code below the problem in order to make a proper alignment. - List from new to old. **Q: (Placeholder) [#h7180d5b] ***A: (Placeholder) [#h8e5e579] *Report [#ud6b560a] This part is basically written by Daria-san. Any other people can add this. Here the information should be from new to old so that we do not need to scroll. **September 6 [#p6587163] - Solved the problem with oscillations in dielectric function. To do: - Calculate absorption for parallel and perpendicular light polarization. **September 5 [#p6587163] - Checked how the dielectric function calculations works with different number of k-points. Understood, that the problem is not in this number, something else. - Checked what method is used for matrix element calculation by Nugraha-san. - Managed to run job at tube60 in background mode, changed a little bit original code to get possibility to use standard input and output files. - Discussed with Shoufie-san the way he calculated plasmon in his thesis, also we had a look at EELS study of CNT and graphene, discussed Sasaki's paper a little. To do: - Add verification of energy difference in dielectric function calculation. - Read Sasaki's latest paper, prepare a review of the paper. - Calculate joint density of states (jDOS). **September 4 [#p6587163] - Discussed with Prof. Saito and Nugraha-san, Shoufie-san the current state of the project. - Created web-page for daily report. - Added one more method for calculation of imaginary part of dielectric function in Nugraha's code. To do: - Check the dependence of dielectric function calculation on number of k-points and frequency points. - Read Sasaki's latest paper, study and compare our results with his. - Calculate joint density of states (jDOS). - Study to run jobs on tube60.
