共形边界态的费米化

Fermionization of conformal boundary states

Hiromi Ebisu, Masataka Watanabe

摘要:

我们利用玻色子对应物的边界态构造了二维费米子CFTs的完整边界态集。我们看到有两组边界条件,它们通过具有整数系数的字符或具有$\sqrt{2}$乘以整数系数的字符来贡献开弦配分函数。我们认为,使用[JHEP 09(2020)018]的论点,该$\sqrt{2}$表示单个未配对的Majorana零模式,并且这两组边界条件互不相容。最后,我们提到一个可能的解释的结果在纠缠熵的文件。

英文摘要:

We construct the complete set of boundary states of two-dimensional fermionic CFTs using that of the bosonic counterpart. We see that there are two groups of boundary conditions, which contributes to the open-string partition function by characters with integer coefficients, or with $\sqrt{2}$ times integer coefficients. We argue that, using the argument of [JHEP 09 (2020) 018], this $\sqrt{2}$ indicates a single unpaired Majorana zero mode, and that these two groups of boundary conditions are mutually incompatible. We end the paper by mentioning a possible interpretation of the result in terms of the entanglement entropy.
