论文摘要
在$（1+1）$ - 尺寸的galilean保串场理论（$ gcft_ {1+1} $）的类别中的两分状状态的奇数纠缠熵（OEE）是通过适当的副本技术获得的。在这种情况下，我们的结果与$（2+1）$ - 尺寸渐近平面的几何形状双重划分为$ gcft_ {1+1} $的纠缠楔形横截面（EWC）（ewcs）。我们发现，我们的结果与奇怪的纠缠熵与两部分状态的纠缠熵之间的二元性以及用于平坦全息方案的大量EWC一致。
The odd entanglement entropy (OEE) for bipartite states in a class of $(1+1)$-dimensional Galilean conformal field theories ($GCFT_{1+1}$) is obtained through an appropriate replica technique. In this context our results are compared with the entanglement wedge cross section (EWCS) for $(2+1)$-dimensional asymptotically flat geometries dual to the $GCFT_{1+1}$ in the framework of flat holography. We find that our results are consistent with the duality of the difference between the odd entanglement entropy and the entanglement entropy of bipartite states, with the bulk EWCS for flat holographic scenarios.
