D3氏と御茶会

今日は研究室で御茶会をした.

といっても,前の研究室の先輩,D3氏との二人だけだが.


彼にはチャットでいつも数学のアドバイスをもらっている.
頼りになるのだ.


話題は,
新竹市新竹県,どっちが上位の行政単位か?」
とか,
「”緑葉蝉”は日本ではなんていうか?」
とかだった.

県と市なら,県のほうが上なのは日本だけである.
大陸では市>県>村里だ.
さて.台湾は.

なんと,県の中に市は含まれないのであった.
新竹市新竹県の外に存在するのだ.
お隣さんなのである.

...Wikiでは上位が県,下位に市とあるが,それはどうやら昔のことのようだ?


緑葉蝉は,食害によって茶葉の発酵を促す益虫である.
ダージリンも同じ製法のようだ.

浮塵子,すなわちウンカのことであった.


楽しいお茶会でした.

Good Bye Mr.Gasiorowicz


September is the term meeting and farewell.
...except in Japan.


I can recall vivid scene where I am saying "I will follow you, Sir, as far as I can"
Because it has not been gone a few days yet... from such my statement war-horse shit.


I am sending eight thousands words of thanks to you, Mr. Gasirowicz, You did it...you made this semi-retired Chinese-Japanese translator to a certain Ph.D initial year student of quantum physics.
No your guidance, no present stairway step up.


Just a bit mismatch, for example you're going the rail of on unit system within electromagnetics, that's quite not the matter in center of our road like as a epsilon naught in squared root, let me aware making suit on current issues.


epsilon naught in the squared root...anyway, I would like to say again.
Thanks.


May I read back? when I feel convenient?

Reading PAW becsum @espresso

Using paw pp,
After "scf", when I was trying "bands", I have met titled trouble.


"Reading PAW becsum"<< Root Cause >>

Cannot find out the file "paw.txt" so they siad it.
Copied it from and to where appropriate and see good running.

Derivation of Kramers-Heisenberg eq.

すんません,こんなタイトル書いたら,参考にするために世界の学生さんたちが集まってきそうだ(;ω;)

I am sorry I didn't achieve it yet.
(;ω;)

At first I have referred Sakurai and Messiah.
Because my target material (one review paper) cited those text book.

I feel such books for advanced QM is difficult for me, so I studied QP by Gasiorowicz.

It is succeeded to get backbone of quantization of EM and even derive some crucial part.


The goal is derivation of Kramers Heisenberg (Dirac) eq.
So I have come back to Skaurai and Messiah and ...

Oh god, I have lost way why I cannot go ahead from the first step only one step cannot step out (;ω;)


...now I am studying Gasiorowicz again.
I wonder I can reach the goal only by this book.

WHY.
(・ω・)??


Oh god..

Quantum Espresso ~cell volume relax with fixed c axis~

行き詰まった時はQEでチューニングの練習するに限りまっす(^▽^)

表題の件,2次元材料の計算練習.
真空スラブを付与するんですけど,そっち方向のrelaxはせずにおきたい.


こちらさまから,

これでdo_freeで設定できるんですな!!


良かった(^▽^)
