Kitaev模型的零温Phase Diagram

The Zero Temperature Phase Diagram of the Kitaev Model

Charles Nash, Denjoe O'Connor

摘要:

我们证明了Kitaev模型的无涡区的零温相图与经典二聚体模型的零温相图在同一晶格上是一一对应的。我们发现,该模型一般有三个不同的阶段。在具有$3\times3$基本域的蜂窝晶格上,所有三个相都是可接近的。当耦合变化时,存在两个不同的过渡。新的转变是一个在$B$相的内部打开的有间隙的相。

英文摘要:

We show that the zero temperature phase diagram of the vortex free sector of the Kitaev model is in one to one correspondence with that of the classical dimer model on the same lattice. We find that the model generically has three distinct phases. On a honeycomb lattice with a $3\times3$ fundamental domain all three phases are accessible. As the couplings are varied there are two distinct transitions. The new transition is one to a gapped phase that opens up in the interior of the $B$ phase.
