论文摘要

我们表明,Cardy-Rabinovici模型中的倾斜限制状态是超级构造者,而不是拓扑绝缘子。这是因为他们唯一的大量激发是完全防止电荷 - 安装对分离的字符串,从而导致严格的无限电阻(低于临界温度和/或电压)。这与拓扑绝缘子的典型激活行为大不相同,这是由有限的散装能量隙引起的。

We show that the oblique confinement states in the Cardy-Rabinovici model are superinsulators, not topological insulators. This is because their only bulk excitations are strings that completely prevent the separation of charge-anticharge pairs, causing a strictly infinite resistance (below a critical temperature and/or voltage). This is very different from the typical activated behaviour of topological insulators, caused by a finite bulk energy gap.
