A topological insulator acts like both at the same time, which we used to think was impossible!

一个拓扑绝缘体就像两个同时起作用，而这在过去被我们认为是不可能的。

All right, let's begin. Show of hands, who here is familiar with the concept of topological insulators?

好吧 开始上课 请举手告诉我 在座的哪位对拓扑绝缘体的概念比较熟悉？

Nowadays, scientists are working to develop topological insulators, and some think they could be as important for future technologies as semiconductors are today.

当前，科学家们正在致力于研发拓扑绝缘体。其中有些人认为拓扑绝缘体对于未来的技术就像今天的半导体一样重要。

One example is called a topological insulator.

一个例子叫做拓扑绝缘体。

Thouless and the final winner, Duncan Haldane, are both also using topology to pave the way for a new kind of material: topological insulators.

索利斯及最后一位的获奖者邓肯·霍尔丹都用拓扑学为一种新物质——拓扑绝缘体开辟了道路。

The edge of such a topological insulator has perfect electron transport: no electrons travel backward, no energy is lost as heat, and the number of conducting pathways can even be controlled.

这种拓扑绝缘体的边缘具有完美的电子传输：没有电子向后移动，没有能量作为热量损失，甚至可以控制导电通路的数量。
