论文摘要
研究了球形单肌缺陷对纠缠熵和中央电荷的$ C_T $的影响，该$ C_T $ $ C_T $在奇数球上传播的自由共形标量场。当上面的范围范围$δ$上，中央电荷也会变为负，对反射阳性有可能的影响。这项工作主要是数字的，但封闭式的表格是针对$ z_2 $ monodromy（$δ= 1/2 $）的，产生了显式$ d \ to \ infty $ limit，$ c_t \ to -6/π$
The effect of a spherical monodromy defect on the entanglement entropy and central charge $C_T$ of a free conformal scalar field propagating on an odd-dimensional sphere is investigated. As on even spheres the central charge becomes negative for a range of the flux parameter, $δ$, with possible implications for reflection positivity. The work is mostly numerical but closed forms are found for the $Z_2$ monodromy ($δ=1/2$) yielding an explicit $d\to\infty$ limit, $C_T\to -6/π$
