标题： Anti-topological crystal and non-Abelian liquid in twisted semiconductor bilayers

摘要： 我们证明，在扭曲双层MoTe$_2$的半满第二莫尔带中，电子晶体与非阿贝尔分数陈绝缘体竞争激烈。 根据扭转角度和微观模型，这些晶体可以具有非零或零陈数。 后者依赖于第一全满子带（+1）和第二半满子带（-1）之间的贡献抵消。 因此，我们称其为反拓扑晶体。 令人惊讶的是，即使在给定谷中的最低两个非相互作用带具有相同的陈数+1，这种反拓扑晶体仍然出现。 反拓扑晶体是一种新型的电子晶体，可能在填充因子为$n > 1$的多陈带系统中出现。 显示英文摘要

摘要： We show that electron crystals compete closely with non-Abelian fractional Chern insulators in the half-full second moir\'e band of twisted bilayer MoTe$_2$. Depending on the twist angle and microscopic model, these crystals can have non-zero or zero Chern numbers. The latter relies on cancellation between contributions from the full first miniband (+1) and the half-full second miniband (-1). For this reason, we call it an anti-topological crystal. Surprisingly, it occurs despite the lowest two non-interacting bands in a given valley having the same Chern number of +1. The anti-topological crystal is a novel type of electron crystal that may appear in systems with multiple Chern bands at filling factors $n > 1$.
