■ [misc]目印

私的なデータベースなので、私以外の人は使いづらいでしょうね。

少し方向性が見えてきたかな。まず、サンプル名(TlCuCl_3とか)で検索できることにはけっこう価値がある。そしてどのような系(Haldane系)についての論文か？というのも重要な情報だ。

カテゴリで分けているけど、すべてを分類して検索するために使う必要はない、と気がついた。例えば、[exp]とか[theory]とかそれで検索する意味はない。でも、他のもので検索した後に、実験か理論かがすぐわかるのは少しは意味がある。また、[calculation]とか[computation]とか同じ意味で使っているけどそれで検索することはないから、別に困らない。あとあとのために数値計算の手法([QMC]とかね)くらいは書いておくと良いかもしれないとは思う。

現時点では少なすぎるから役に立たない。協力者募集中・・・ってこんな暇なことしようと思うやつはいないか。googleで検索したほうがまだいいかもしれないし。まぁ、これは私の勉強のためなので。自由にやりたいと言うのもあるしね。

■ [misc]これからのこと

新しいものを中心に少しずつ増やしていくつもり。だけど、おなじ物質を一まとめにアップとかもしたい。あとlecture noteやreviewなどがあれば古くても載せたいとは思う。

さらに先のこと。

量子スピン系の研究を続ける限りこのページは続けて行きたいけど、研究をやめてしまったらこのページの更新はなくなると思う。そのような場合には誰かが引き継いでくれないかな、っとは思う。できれば実験系の人に引き継いでもらいたいのだけど。まぁ、これはまだまだ先のことで、他に考えるべき重要なことがいろいろあるわけであって、比較的どうでもいいことではあるんだけど。
