本文在二维量子自旋系统的算子代数框架中定义边界态,并证明其边界 C*-张量范畴的 Drinfeld 中心对应体编织范畴。

摘要:

我们在二维量子自旋系统的算子代数框架中,引入了体有能隙基态边界态的自然数学定义。利用边界处的近似 Haag 对偶性,我们从此类边界态导出一个 C*-张量范畴 \tilde{\mathcal{M}}。在体中编织非平凡的条件下,我们证明 \tilde{\mathcal{M}} 的 Drinfeld 中心(带有渐近约束)等价于文献[14]中导出的体编织 C*-张量范畴。

英文摘要:

We introduce a natural mathematical definition of boundary states of a bulk gapped ground state, in the operator algebraic framework of $2$-d quantum spin systems. With approximate Haag duality at the boundary, we derive a $C^*$-tensor category $\tilde{\mathcal{M}}$ out of such boundary state. Under a non-triviality condition of the braiding in the bulk, we show that the Drinfeld center (with an asymptotic constraint) of $\tilde{\mathcal{M}}$ is equivalent to the bulk braided $C^*$-tensor category derived in [14].
