典型的な電荷密度波物質である三セレン化ニオブ(NbSe_3)のリング結晶を用いて、電荷密度波のダイナミクスにおけるトポロジー依存性を測定した。電荷密度波物質は、低電場では強誘電体のように振舞うため、交流伝導度測定が有効な測定方法である。閉じたリングの状態と、収束イオンビームを用いて切断したリングの状態で、電荷密度波ダイナミクスがどのように変化するかを測定した。その結果、閉じたリングのピン止めポテンシャルが、切ったリングより小さくなっていることがわかった。この原因として、リング内部に電荷密度波環流が存在している可能性を提案した。この結果はPhysical Review B v 73,p165118(2006)に発表した。NbSe_3リング結晶の発見以降これまでに発見されたトポロジカル結晶は、リング、メビウスの帯、8の字(2πひねりリング)の3種類だった。本研究では、リング結晶の収率がよい三セレン化タンタル(TaSe_3)を用いて更なる新しいトポロジー的構造を持つ物質を探索した。その結果、リングとリングが絡み合った結晶を発見した。この構造は、数学ではHopfリンクと呼ばれ、最も基本的な絡み目である。この発見は、トポロジカル結晶を含む新しい結晶学を構築する上で、重要な位置を占めると考えられる。この研究結果は、Journal of Crystal Growth v 297,p157-160(2006)に発表した。

A typical density wave with high density (NbSe_3) is used to determine the dependence of the density wave. There are many methods for the determination of density waves, such as load density wave, low power field, low power field, vibration and dance, AC temperature measurement and so on. This is the first time that the density wave has been cut off and the density wave has been measured. Please tell me the results. Please tell me that you need to know that you are not going to have any trouble. The reason for this is that there is a possibility that there is a proposal for the existence of density wave flow. The results showed that Physical Review B v 73 ~ (th) p165118 (2006) was successfully used in this study. The results of the NbSe_3 test show that you can see the difference between the two. You can see the difference between the two, the number of characters (2 π), and the number of characters. In this study, the results show that the results show that the equipment is used to improve the quality of the equipment (TaSe_3). In this study, the results of the experiment are as follows: in this study, the results of this study are as follows: in this study, the results of this study are as follows: in this study, the results of this study are as follows: in this study, the results of this study are as follows: in this study, the results of this study are as follows: in this study, the results of this study are as follows: in this study, the results of this study are as follows: in this study, the results of this study are as follows: in this study, the results of this study are as follows: in this study, the results of this study are as follows: in this study, the results of this study are as follows: in this study, the results of this study are as follows: in this study, The results of the results, the results, the results. You need to know how to build things, how to Hopf in mathematics, how to do things, and how to do the most basic things. The results show that there are some new results, and the important position occupies an important position. The results of the study, Journal of Crystal Growth v 297, p157-160 (2006).
